Review: The new HaikeLite MT07 - Buffalo XHP70 thrower

This is a review of the new HaikeLite, a new manufacturer, model MT07 Buffalo. It's a XHP70 thrower with a big reflector that can get a lot of light down field. HaikeLite provided the light for this review. So far I'm very impressed with it - the quality and styling, plus it's real easy to take apart and get at everything. It's a big light, no doubt, but you need a big reflector to get distance, and a lot of mass to handle the power and heat the LED puts out. The 4 18650 cells do well, but it would be nice to have an extension option to double them up to 8.

Tripod mount, opposite side of the switches. Nicely set in SS piece:

The round plate below is floating, swivels so it stays locked in place while screwing on the end cap. Those springs are beefy and tight. The Batt+ ends are protected by a black hard plastic guard - true flat tops won't make contact. The alignment rods are two different sizes so can only go on one way:

Showing the 30Q BT's all set to go. It's a 2S2P arrangement - the light can actually be run on only 2 cells, one pairs of 2S:

True square threads, good quality double up o-rings:

This is the battery tube, the end butting up against the driver springs shown above:

A look down the battery tube. The cells fit snugly in there:

The S.S. bezel came off very easy, but still tightens up well enough not to accidentally loosen. The double AR lens looks well made, plus a big o-ring between the glass and reflector:

This driver retaining ring is one of the heaviest I've ever seen. It's either SS or plated brass, but weighs a ton HaikeLite said it's silver coated copper! Wow!! That makes more sense considering it's weight. The finish is flawless so could not spot copper anywhere:

Proof of it's heftiness:

User Interface

It's described pretty well up top, and it's pretty simple. Pretty nice two button UI, where the lower one is ON/OFF and upper one is mode changing. It has mode memory, quick access to turbo via a double-click on the ON/OFF button, and a double-click on the upper mode button display moon mode.

So there are 6 levels of output total, with 5 (not moon) in the main mode cycle.

In addition, a press&hold on the ON/OFF button activates strobe, then the next press&hold activates SOS.

The mode change button has LED's behind it, and indicate a crude battery level status, using a blue and red onboard LED. I haven't tested this yet, but the blue LED stays on when the light is on, with the cells being over 50%.


Well, this sure does remind me of a Shocker - a large light with a lot of power. But really it's a modernized version with a quite a bit more class and style, more powerful LED setup, and an improved power source of 4 cells instead of 3. In it's stock configuration, the sheer amount of lumens and throw is impressive.

It's also a style very familiar to me - reminds me of an up sized BTU PK26 with it's short battery tube, and styling of the head area - similar look. What I really like about these short and stocky, powerful lights is their tail standing is ideal,and the MT07 is rock solid with the head up.

For the reflector size, the XHP70 really throws well. Of course a SMO reflector could help improve it further, but then you have will probably have the dark lines in the hot spot.

It appears to be top heavy, but I find it quite well balanced in the hand, but you do have to hold it on the fins for a balanced carry, then it's prone to getting your hand uncomfortably warm/hot on turbo.

I did do a 6 minute run on turbo with the head temperature rising to about 110F (42C), worse spot, when I shut it off.

The parasitic drain of 0.280 mA I measured was running on just one pair of cells. It should be noted the 0.280 mA is across 2 cells, double the cell voltage, so equivalent to a 0.560 mA in a parallel configuration. It's a little high - I measured my modded Convoy L6 at 0.062 mA across 2S cells, using a Texas Avenger LDO tripled channel board, so the MT07 is little more than 4 times as high as the custom FET and LDO based board running Narsil firmware.

Another issue worth noting is the battery size and type configuration support. They clearly state high drain flat top cells, but' I've found the more common flat tops don't seem to work. SANYO GA flat tops work well, and some unprotected button top cells, like the 30Q seem to work well, though not sure if the end cap can be screwed/tightened down as much as with the SANYO GA's. The GA cells have a protruding top, so it's almost a 1/2 button top. HaikeLite has had more luck than I using flat tops, so we need to understand this better. Ideally I would have liked to see exposed contacts for the batt+ connections rather than the plastic ring around the contact surface. I believe the intent is a mechanical reverse protection, but it doesn't seem to work well with true flat tops. I've already had discussions with them on this issue - hopefully we can clarify this further. I just might remove the plastic pieces altogether, unless there's something I don't understand, or my one piece is different somehow.

Overall though, I'm very impressed with this light. It has all the advanced features and performance they specified. The lumens and throw are right there, well within the margin of error. My throw #'s were measured at 5 meters - too short for proper focusing of a true thrower, and I'm almost certain at 10+ meters, the kcd would be a little higher. As a stock light, it's an outstanding value for the cost, and as a light to mod, real easy to dis-assembly and work with, specially with the 2S2P configuration, and it's thermal design, it's made for a high performance 6V LED FET based driver design, or possibly experimenting with the current limiting resistors.

Update 11/11/2016:

Runtime discharge curve for Turbo mode. Samples were taken at 30 secs in the beginning, to every 15 minutes towards the end. Chart is properly scaled now, and tempterature in C has been added:

They'll be more to come to add here, including some white wall comparative beamshots. Just an fyi, the spill area is tighter than a Convoy L6, but clearly the spot is more intense. The deep reflector will tighten the spill width, and the larger reflector width increases throw.

Edit/Updates 11/15/2016 - Wallshots:

This first series is of the MT07, N4 CW, in all 5 modes, followed by the Convoy L6, N4 CW, in all 4 modes

Now the L6:

Update 11/17:

These are taken from a longer distance back, comparing the MT07 to a Convoy L6 (another one - black N4 2A). I think it represents the hot spot better, from what I' seeing, though the rings shown around the hot spot in the pictures I can't see in real life.

November 20, 2016 Update:

Took some outdoor shots last night at a local park - Edgewood Preserve, site of an old hospital long since demolished, and rumored to still have some spirits haunting the trails (info). The park closes at dusk but can still access it, just dunno if I'd get kicked out, but last night was all quiet. Here's the old hospitial from the 40's:

Took a few lights with me, mostly throwers, to compare with - all modified. I'm not pleased with the quality of the shots. Will be spending more time on improving my setup. hey didn't look this bad when previewing on the back of the camera - should have brought my close up glasses.

For this sequence, here's the range at the site, 536 feet, about 163 meters:

First up, Manker U21, modified w/dedomed XPL V6 0D, ~240 kcd, ~1,700 lumens:

Next is a UniqueFire 1504, dedomed XP-G2 S4 2B (good one), ~540 kcd:

BOSS1, dedomed FastTech XPL V6 0D, ~700-740 kcd:

TrustFire 9X, plunger style, ~6,500 lumens:

Convoy L6, supposed N4 2A, but warmer, maybe N2, modded with FET+1, LDO, Narsil, ~5,800 lumens, 124 kcd:

Finally, the MT07 stock, N4 CW, ~4,730 lumens, ~132 kcd:

The 5 modes of the MT07:

Here's the modes shown at a shorter distance, about 75 feet:

The lights tested/compared:

Hey mate its heavier then the MT03 unless my scale is broken lol. It must be the reflector and the extra length i guess?

Great review Tom E. If their run times are anywhere near actual, run time is excellent putting out that many lumens. Had no idea the XHP 70 was that efficient.

The driver retaining ring is made of Pure Copper with Silver plating to enhance the electrical conductivity . SS material will eat the voltage and runtime.

Thank you for the great review, Tom. :slight_smile:

Tom do you have outdoor beam shot comparison with other monsters flood thrower?

If this performs better than the L6 I’m so getting this

Thanks for the review Tom, It seems like we have a winner here! According to your measurements it should out-perform a L6 with great margin specially in throw. I really like the level of attention to details, everything seems to be designed with performance in mind.

The standby current is a bit high but if all 4 cells are in place it would take more than a year to discharge them to 50%, I guess that’s acceptable

Would like to see how well it regulates after the step down, and some outdoor beamshots of course :smiley:

Thanks for the fast review, Tom!

Wonder about the current draw at highest level. For this output it should be driven hard. I doubt a resistor mod will increase output much. In comparison with a L6 we have on the plus side the UI with two momentaries and some more output of lumens und lux in stock version, but with a simple resistor mod the L6 will almost catch up the output. On the other hand the L6 is more handy (I guess), and half the price.

Great review Tom E! Very nice pics and description also! I like the Buffalo!

Looking at the anodized threads and the battery tube contact to driver contact this can be mechanically locked out?

The battery tube + contact looks to be a normal PCB do you know if the trace thickness is re-enforced in this area?

Great job Tom! Got’s me wanting (not needing) one!

Maybe change out the two resistor’s to a couple R050’s for a boost! Add a copper disc to the battery tube contact for wear resistance. Change the emitter to a higher Bin P2 and a close shave! :wink:

Thanks for the elaborate review and the pictures! :THUMBS-UP:

Do we have a winner?

That would depend - as always - on the final price.
Yes, it does throw - somewhat. I would not call 132Kcd a true thrower in a light this big - but it will outthrow the Convoy L6.
Again, the price will be part of the equation.

It looks like a good and well made light, ano, ar lens, design, threads, o-rings, driver plate, dubble springs, all looks very good. :THUMBS-UP:
But those switch rubbers look cheap - to me at least. :FACEPALM:
I would have liked to see metal switch plates, which would make the light look a lot better.

I like the comparison with the BTU Shocker, being a 3 year old design.
Bear in mind, after modding mine does 360+ Kcd and well over 3500 Lumen.
If I can find the right driver, I will probably update it to 3 * XHP 35HI………we’ll see about the comparison then! :wink:

Now THAT I call a thrower with high lumen output.

thanks a gain for this great review!


Of course it will outperform the L6 … 3000 vs. 5000 Lumens and much bigger reflector.
A true competitor would be the Acebeam K60 right? I´d love to see comparison shots with the K60…


Very similar numbers to the K60. 4950lm 160kcd.

Ohh, thanks! Now that you mention it, it sounds familiar - you probably posted about it before. I'll update that note I have on it.

I can do a mech lockout on the threaded connection at the driver, not the tail end. Slight twist of the battery tube breaks the connection - the silver coated copper retaining plate connection gets broken.

If you mean at the tail, the PCB f the tail has huge traces, wider than the springs, between the batt+ and batt- connections. On the driver side you got that hunk of silver coated copper - crazy, never saw anything like it, but probably in some other high end lights.

Thanx! My thoughts as well. Would like to see what it can do in kcd with those tweaks.

I didn't mention it - still wanna confirm it, but I used a set a couple more sets of cells and got different results, some close, one set of readings was a bit more off - actually higher (SANYO GA's rested @4.14V), weird though after fully charging them, I got lower readings. On a set of VTC6's w/solder blobs on the batt+ end of the cells, I measured 3.1A on one 2S pair with the other pair jumpered in (should be 6.2A then?). Then on just one 2S pair driving the light, I measured 7.0A. I got slightly higher lumens on the VTC6's, even with the cells at only 4.12V.

For the lumens numbers, bottom line is I am getting, some lower than 5K, some higher, but mostly lower, so the 30Q BT measurements I consider fair, but straight flat tops could do little better, and all within a 5% margin of error.

I'm on 3 hours sleep, and at my age, it's tough...

Totally agree here, though I'm not a fan of AceBeam anything (I only have a modded K40 under the SupBeam name), but I said that a while back in the MT07 thread about comparison with the K60.

The MT07 is a bigger light - should be heavier. Dunno if the MT03 has one, but the driver retainer plate in the MT07 weighs a ton - I should have taken a pic of it on the scale, now that I know it's solid copper .

All true, agree. I've gotten over 500 kcd on modded Shockers, also 1 or two over 5,000 lumens. The Shocker was a modder's platform in my think'n, but this MT07 does well stock, but can be tweaked, of course. Yea, hear you bout the switches - do look a little out of place on this light, but the LED's under the top switch are look' nice, and they feel really nice. Would be nice if a couple spares were thrown in - I can see these ripping eventually - they are very grippy, but sticking out like that, very easy to find.

The Shocker II will be a totally different class than the old one, and will certainly be in the 3X level in lumens compared to this light. Think'n more like Dale's Super Shocker mod going into production...

Ohhh - I think we do have a winner with this one, both for stock performance/price, and modding. Hope the battery fit issue isn't a biggie though. I'm sure we will hear more about it.

How long might it be until we see your resistor mod? Please wait to respond if you already have your soldering iron in hand.

My personal worries is that the light is not going to maintain it’s output. Instead, output significantly reduces with time resulting in such high runtime values…

Well of course it has a stepdown, in fact the info is right there in the OP:


I don't really have a good setup for long runtime tests using the PVC light box. But it's mentioned in the specs that turbo knocks down at 5 minutes to 2800 lumens. So they are quoting 8 hrs on turbo, but that's not at turbo output levels - same thing the other manufacturers do. Til we get true output curves, hard to say what is really goin on. I could attempt doing it but hard to find that much time - would have to babysit it since I would not trust the setup.

If turbo was pulling about 6A from the cells, 3A per pair, then 2 hours at a minimum is legit. If they measured 8 hours, then power is being backed down during the run. I measured 6A-7A at the tail using a clamp meter.

Edit: Ooopsie, I got this wrong. 3A per pair is 1 hour roughly on 30Q's, 3.5 hours on SANYO GA's. Forgot it's 3A draw per cell when measuring 3 amps for 2 cells in series.

2300 lumens for 10 hours?

Very nice review Tom, thanks.

Hope to see some good beamshots soon
