Review: The new HaikeLite MT07 - Buffalo XHP70 thrower

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:

K.

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

Nope, must be multiple drops, or at least another big one, goin on to achieve those run times, or amp regulation as voltage drops, slowly dropping output.

I know, that was my post #16. My comment was based on Kusie’s reply #17.

I like it. Shave that XHP70 and you could get up to 200kcd, don’t you think?

It’s funny to me how long and complicated they made their serial numbers though.

Yea I agree - didn't really give much thought on runtimes, but I'll see what I can test in the next few days.

PD - Dunno what the typical bump up is on shaving - VOB I think had good #'s on it. was it 50% up in kcd? Think it was around there...

For runtimes there’s no need for accurate lumens measurements, just an simple ceiling bounce to set initial reference for 100% and then 1-minute interval reading for the first 10 then 5-minute interval for the rest. However without a computer logging light meter one has to sit there the entire runtime and manually enter the data to the chart which is really time consuming…

Man I literally came up with this idea a minute ago. If you don’t have a data logger, why not place a clock next to a lux meter, and record a video with a smartphone? No more baby sitting…

Edit: nevermind the clock; the video has built in timer.

Phenomenal light so far. Thanks for the review!

Guess the only reason for not using the PVC lightbox is heat issues, but could keep a fan goin on the light. For the test, recording of the readings. Smartphone or iPad might do the trick - haven't done much in video recording off those devices, but could check it out.

fwiw I put the 9k X7 in the tube for runtime tests. Tiny fan kept everything just fine, but I imagine even without the fan wouldn’t be an issue.

I carve out a few hours and chill next to the light while I listen to a podcast or something like that and record temp and lux via timed alerts.

Yikes! If I tested all modes, that's 228 + 32 + 18 + 10 + 8 + 98*24 hours, or 2,648 hours.
Ok, without moon mode it's only : 296 hours, or 12 1/3 days - not bad . I'd only lose 8 days of income, several $K there, (I only get paid for hours worked), and no sleep of course .

Ok - maybe only turbo... Just one full work day or long evening...

Might have to figure a way to work @home while this goes on... Hhhmmm, or be able to bring everything into work and watch while typing away... Might be do-able .

There are probably expecting to sell A LOT of these lights. :smiley:

Now we wait…….for the price. :wink:

i think this light can very well compete with the acebeam k60 as far as performance. 5000 lumens and 132kcd is respectable. but i agree with what dbcustom said…its pretty much last years numbers. I would have liked to see 6000 or more lumens. considering the size of the heatsink, i would have expected longer runtime than 5 minutes on turbo. most lights can only run turbo for 2-3 minutes, but their head and heatsink is nowhere as large as this mt07. my modded tn36ut can run at 8000 lumens for 5 minutes, and its alot smaller.
i’m not sure if haikelite will be coming out with a smo reflector for this light, but if not, shaving the dome will be a good idea for a light like this. vinh said shaving the dome off of xhp70 on a op reflector makes the beam perfect and completely eliminates the donut hole effect. at least this is what happened with the k60.

i like the fact the light is under $100 and great value for what you get. the double switch and ui is great. and the easy to mod makes it even better.
but the thing i would like changed is the heatsink or the handle. im guessing its too late now to change the design up drastically. but i think the light should have been 1 inch shorter at the head. it seems very top heavy. and since i think the diameter of the reflector matters more than the depth for throw, it would have been very minimal decrease in the throw department. this way, the user can hold the light by the handle and the smooth surface where the switches are…instead of holding the light by the handle and to the heatsink.

ps. the price has been listed….its $95
