It is too late to sign up.
But gearbest have them already for sale, they (as far as I know) have 100 pieces in stock and since we have a confirmed 60 pieces there should be enough. I’ll send you the coupon code so you can order it.
Can this driver utilise e-switch? because there is a soldering point with “Key” printed beside? (Presumably other lead would be soldered to ground but I am not sure, that would be 8.4V thru teeny tiny e-button)!
So with 1.5A you get about 2000 lumens. But the XM-L2 can be driven at 6A with copper DTP, resulting in about 1600 lumens or so? A few hundred lumens less which is not so visible, but the smaller die results in (much) higher lux values with the XM-L2 or not? So what makes this LD-51 driver so interesting?
I’m not sure of the exact numbers but you have to convert the power usage to watts to get a better perspective. If the XHP35 is a 12 volt led, 12V x 1.5A = 18 watts.
XML2 leds will only go to a max of 5 amps these days. 5A x 3.5V = 17.5 watts.
I suspect that this is pretty much comparable to what I did. With a comparable efficacy this results in higher lux values for the smaller die XM-L2 with comparable lumen values. So what makes the XHP35 emitter interesting?
Its lumen output /the auto industry (mainly due to its working voltage)/oveall 12v applications: at 12v you can straight use it with a siple resistor as a driver
