Review: The new HaikeLite MT07 - Buffalo XHP70 thrower

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

Very nice review of a very nicelight!
(nice they engraved Tom E on it, can we order them with a custom engraving too :wink: Lol joking)

Just turbo would be nice. Not even the whole run would be necessary. It would just be good to be able to see how far they drop it down in order to achieve 8 Hours.

That has to be a ridiculously massive drop to squeeze out that much time.

For the runtimes, I'm getting curious now. I'll ask them as well, but still would like to do an independent test.

For the S/N, I was trying to figure it out. After the year it's a letter, 3 digits, letter... repeating... and the #'s are 0002, 0003, 0004, and the letters are: H-A-I-K-L. Interesting... There were a couple more review units sent out. I've been pm'ing with bluzie and he's getting the MT03, but got messed up in customs so still another couple weeks.

It might have extra data in it like a vin.
