Black Bullet X - 1.000.000 Lux/Candela

Hi i spend some time to build my Black Bullet X. Some Details:

- Trusfire X2 Host
- Cree XP-G² R5
- Sinkpad Copper Star
- PCB-Components AMpere Buck Driver (5.2 Amper out)
- Wavien RLT™ Collar
- 78mm Glass Lens
- 3 x Efest 18650 3400mA/h Cells

I messured 10.500 Lux at 10 Meters distance. That are back calculated to 1 Meter: 1.050.000 Lux/Candella.

This light is only for demonstration how far a single LED light can throw. It is not perfect now, cause the values are fast sinking to 950.000Lux. This is cuase by the thin heatsink. If i have more time i will build a new on out of copper.

Pictures:





Details and inside pictures will follow.

Amazing!
Did you dedome the XP-G2?

Let's hope you get the heatsinking figured out and make a couple more of these

Wow. That first picture is just amazing. Talk about a light-sabre!

Holy slice. That is sweet.

mash.m, would you consider making any more of these for some of us (with a big Cu heatsink)?

Hi, i am waiting for the responce from wavien. At this moment i do not know anything about their licens model. Then i will see if i make a small batch of these.

What a great first picture! Perfect time of day. That must have taken some planning! Yeah, that does look like a great light to get.

Ditto,
I am hoping this XPG2 is in tact! which would make it more amazing!

Put me on the list if you end up selling them!

Hi,

the XP-G² is without Dome. But this is a first shot. A dedoming doesn´t double the Values with the collar. I will make some additional tests with a xp-g² with a dome and post the values here. also some details pictures. nothing is secret!

markus

de-doming doesn't double the value but does increase its throw due to the smaller image projected by the lens. It'll project a tighter and brighter beam over the domed version. I have tested this before I sold my light and to the eyes, it is considerably brighter and better at throw.

hi matt, you are right and wrong. dedoming nearly doubles the output values of throw that is messured in lux/cd in a normal lens/reflector setup. you can easy messure this with a lux meter. it does not double the overall light output that is messured in lumen!

+1 here - put me on that waiting list too. That light is a "must have" - hope wife approval isn't required....

Put my name on the list if you ramp up...Thank-U

When I used to measure Lux and Lumens on SST-90, SS-50, XR-E, ect.....
I found the dedome process would give at least a 30% increase in Lux. Regretefully; the OTF lumens dropped 20~30% and depending on the heatsinks sometimes more loss in OTF.

On my SR90's SST90, dedoming almost doubled the cd (~87% higher).

The lumens hardly dropped though, ~ 200 lumen, but, I had no baseline, and was going by Selfbuilt's et al lumen measurements as a consensus "before" OTF lumen output.

Of course the light sags significantly on lumens output. The image of the die is no longer amplified and controlled by the missing dome originally placed there by the manufacturer. De-doming is fun but if the phosphor is missing, it ruins everything behind and aspheric
