An XP-G3 can take direct drive from a single cell at up around 6.6A, as can the Nichia 219C (top cells might be too much though). The XHP-50/70 and MT-G2 can take direct drive from 2 cells with the XHP-70 and MT-G2 easily doing 12A on top 26650ās.
The XP-E of course has issues with an FET driver. The XP-G2 will limit itself through a high Vf to around 4-4.6A. A buck driver from Richard can do 5.5A to the XP-G2 through 2 cells.
Edit: To make it easier to stack chips on a Qlite style driver, remove the spring first. Then youāve got a clearer shot at the legs. Put the spring back on when youāre done. I tend to do my stacking on the inside, starting with the one where the negative leads comes off and then going across to the other side as those two have the least room on that one leg near the MCU. Then do the two that are opposite the MCU and itās fairly easy. Stacking another row on top of all those is fairly easy too. Thatās what I typically do, go with 12 total chips on the inside, leaving the original 4 on the outside where the spring is. A 1.5 to 2mm bevel tip on the iron helps hereā¦.
Thanks Dale. Iāll give removing the spring ago. This light with unknown dedomed XML2 at 2.8 amps is only 13% down on my HD2010 which has an XPL HI running a 5.5 amp buck driver at around 7 meters. Admittedly the led in the HD2010 could be tuned a little better so the difference would be greater than what it is. Iād love to try a dedomed XPG2 but I wont have the time.
Formula is Distance x Distance x Lux. So on given example it is 5m x 5m x 1000 lux = 25000lux
Of course if you have meters on x10 settings multiply that with 100 before calculation.
And real life usable throw(where you clearly can identify target) would be around 100 meters
For those that have given me advice on how to solder chips on and I failed miserably, well I can now say thanks. I wont tell you how long it took but the driver works and outputs 3.4 amps. Yes Iām a happy camper.
I got a meter reading of 190. That is with three pushes of the button so I get a reading on the screen. I have the same meter as you have. Distance is 8.58m. Iāll let you work it out here so I can note it down. Thanks Dale.
And then it also depends which XP-G2 S4 2B Really I am not kidding you here. New is super bad and you should avoid and put XM-L2 or XP-L or if you have good old one than you are good to go in breaking candela records
Probably new, the old ones are sold out everywhere.
You can recognise the old ones by the die.
They have relatively smooth phosphor and the grid of dots are visible.
The new ones have more rough phosphor and you can hardly see the dots.
Hello, could you tell me what variant of xp-g2 is? I can not get better photography, I have one placed in UF1504, with driver BLF A6 runs at 4.7 amps with fresh cells, greetings!
