Have you seen this 3 x XHP70 soda can light before? (similar to Haikelite MT03)

Sillen:

Edit: First impression, it’s brighter than Sofrn Q8. Will have to wait until it’s dark to do an amateur ceiling bounce. Sure gets hot quick!

Bro! Please do that! Am sure many people would be interested. First impressions seems somewhat ok, though it’s not the 9000 lumens light it was meant to be (never mind the Taobao 13000lm thingy).

By the way, pls also do a ceiling bounce with the BLF Q8. I think i read somewhere that sometimes these ceiling bounce tests might favour the more throwy lights and the Sofirn has 2X the cd over the BLF Q8 which in turn probably has 2X the cd of this light.

And besides, it’s in NW (though not high CRI), so how bad can that be.

PS. What batteries are you using? For sure these need at least Samsung 30Qs.

And if you are saying that it is getting hot quick, it might be gunning those pretty hard. Might even be able to squeeze out more with just simple spring bypasses.

edit - actually in some Taobao links, i am seeing some 7070 emitters rated at 6V 5A. So yes, 30W per emitter. There are some which are 15W, 18W though.

Some folks here might even be able to swap those chinese 7070s out with their spare XHP70s within 10 mins or so, don’t even need to change the drivers if they are driving the LEDs decently hard, meaning that with XHP70s the light would be putting out more light while running cooler. The possibilities……

Then next week after the holidays i might try to get it for under rmb 300. Maybe tomorrow even (most of them are already working esp on TB), counting on you Sillen!

I like this little corner on the benchtop ’cause it’s all white’ish. I put Samsung S7 between the bowl and the lux meter sensor. S7 using Lux Meter app.

Results are:
D4S XPL HI 680
ROT66 Nichia came with VCT6 from Neal (blinks 4V) 1070
BLF Q8 VCT6 from Oz (Blinks 3.8V) 1200
Sofirn Q8 VCT6 from Oz (Blinks 3.8V) 900
S41 Nichia 250
Rome Q30 Banggood supplied 30Q’s (Measured 4V) 1400
S70S 800
BLF A6 260

Winner

Thank you Sillen. Very useful result for me also, as i’m also looking to get a ROT66 with the 219B emitters.

It looks to be around 6000-7000 lumens stock depending on how you look at it. Not too bad.

Not too bad?
You can get this from a single XHP70.2

Not at the price that i am shooting for at about rmb 300 (43usd or below). It would be a practical budgetlight league for sure. There is also a practical side of things as i do not like to use my expensive stuffs out there for “trashing”.

The efficiency with gunning a single XHP70.2 to 7k lumens is already gonna be…… :weary: Gonna gain throw of course.

The UI is not too bad, of course it’s not like the BLF Q8. There is not too much duplication to the Q8 in real world apps also as this would be quite a fair bit floodier.

The other one that i am shooting for is Nightwatch NA40, about usd 39. 6000 lumens 3 x SST-40. Another budgetlight that i can really use outside + fit into the pant pockets even more easily, and uses 1 x 26650 so i don’t have to get another set of 4 x 18650($$:money_mouth_face: for it.

Personally, I would just buy this light as a host.

eas · 2018-10-05T18:51:23.000Z

Thanks for the test. It would be good to see a comparison with the other multi-emitter lights where all have freshly charged cells.

That’s charging 15 cells all at once. Was too lazy last night. Sad thing is I can charge that many at once even without breaking out the Lii402. What have I become!

Might try out the dedicated lux meter too. It was pretty close to the s7 sub 1000lux but over 1000 lux it started showing much higher readings

3 x XHP 35 HI swap? Haikelite MT09R 3 x XHP 35 but with more throw? Haikelite MT07S 1 x XHP70.2 netural white but with more throw and possibly more lumens?

Economical enough too as long as the light’s base price is low enough. I am wondering if the focus is going to be ok, anybody has come across similar mods? (single or multi emitter)
Thermals need to be perfect though, maybe need a sand-down of the host-emitter surface and using all the known tricks. I think this light stock is gunning ~ 20W to each emitter, thus gonna be overdriving the XHP35 HI decently on the stock driver, which is of course what we want.

Anyway, for single XHP70.2 generally available lights, the Haikelite MT07S gets 4500 lumens in neutral white (usd 52 lowest price that i could get). The Acebeam K60 thrower (88mm head anyway) is 5000 lumens in CW.
Not apple-to-apple comparios, but just for ref.

2100 · 2018-10-05T23:32:25.000Z

Talking about low base price, the sellers i have asked on Taobao would not go below rmb 318.

I wanted rmb 268, usd 39 A lucky number in Cantonese. Shipping would be part of my consolidated forward order from the Dongguan Guangdong warehouse that i use, ie very cheap. Even without modding, i believe playing with a usd 39 6000-7000 lumen stock light is pretty decent. (might comfortably hit 7k with spring bypasses), comparing to things like the BLF Q8’s best price.

Sigh….maybe i shall wait till the end of the year and try again.

You can do it with just 4 cells and things like the Miboxer C4-12A. 3 amps each channel is possible on the lowest internal resistance cells like the VTC5A till the very last bit.
Pop the used cells into the charger, grab a coffee and within 5 minutes you ought to be able to start on the next light.

@2100, do you want an even lower price for the MT07S XHP70.2?

Go on M4DM4X.com and sign up. You’ll get it for 46,50$.

Just checking things out buddy, M4DM4X.com is new to me and would be very useful. Just came back to the hobby after a few years break. Thx for the heads up!

2100:

3 x XHP 35 HI swap?

This reflector is very shallow and OP. I think it would make a terrible thrower.

Yeah i suppose so. At this size, even after consider all options to mod etc, it’s like trying to be a jack of all trades but a master of none.

The soda can size is pretty ok though. Taking the Mateminco MT18 with its 72mm head for eg, that is really quite a bit on the big side to use practically and then “stuff it into the pocket”.

Lexel · 2018-10-07T10:28:17.000Z

One thing I didnt like on MT03 was the very thin LED shelf, is this copied or thicker?

Of course on of my new MT03/09S DD+small 300mA FET drivers with BLF firmware would be an option when battery is 2S/2P

Sillen · 2018-10-08T10:20:51.000Z

Ok, did it again with fresh batteries for ROT66, 2xQ8 & Fake MT03 aka Q30.

30Q's in Q8's, VCT6 in ROT66 & Q30

Measured on Lux app on Samsung S7 & LX1010BS. ROT66 stepped down before 30sec, didn't catch the number

	Turn On S7	Turn On LX1010BS	30 Sec S7	30sec LX1010BS
D4	600	650	300	325
D4S	1080	1170	820	890
ROT66	1150	1210	370	390
BLF Q8	1300	1485	1225	1408
Sofirn Q8	1135	1325	1063	1248
Q30	1466	1950	1335	1818
BLF A6	288	319	270	301
S41	370	430	312	364

7.2% drop after 30 seconds for this Q30 at about 6500 lumens, vs Sofirn Q8’s 6.1% (~4500 lumens). Taking BLF Q8 to be 5000 lumens exactly.
My BLF Q8 steps down in 3 mins exactly most of the time +/- 10 seconds.

Not too bad. Should be able to hit comfortably over 7k lumens with bypass,

I need such a light (floodie) for the constant hot weather here.
Was already gunning > 10 mins 2 nights earlier with the Q8.

I can go with the MT03/MT09R etc, but it wouldn’t really be practical/useful for the majority of the time, both size wise (MT09R) and heat wise. Prob only for just 20-30 seconds bursts, esp during the time when the light already is warm with previous lower power uses, unless if i have a water source nearby for host cool-downs.

I already have a lot of experience with my 3pcs of DRY triple XM-Ls gunning at close to 5 amps direct-drive (3S) at the tail in 300g smaller hosts last time, so i more or less know what to expect.

Now to ask for more discounts from the seller(s)……

2100 · 2018-10-12T04:57:52.000Z

Bro Sillen, do you think you could help me with a favour?

Could you pls switch on both the BLF Q8 and this Q30 and duration it takes to hit the thermal regulation point? Both shd be at 55 deg C setting. If you have access to a IR thermo then that’d be even better. Else the auto thermal regulation point is fine.

This is to find out how efficient those chinese 7070 LEDs are.

Thank you!

The BLF Q8 can vary the thermal step down point depending on how off the internal temperature probe is. It is set in software for 55°C, but it could easily go above or below that unless you set it yourself.
