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
Thanks for your input. But I meant what makes the XHP35 emitter with this particular driver interesting for flashlights. For instance, I want to do some emitter/driver swaps with my Convoy L6. Why would I use this driver with the XHP35 emitter, if I can have an XM-L2 at around 5A resulting (I think) in slightly less lumens, but much higher lux values?
Its all about marketing m8, a good binned V6/U4 will give you nearly 1900 lumens output and way better candelas, yet companies use XHP35 cause its new, have more lumens at its default values that XML/XPL and will bring aditional sales
Most of those companies used and are still using Cree XB-H for the same reason: its new, atracive…and they all need your money
Ofc XHP35 is way more usable in a flashlight than XB-H yet its main idea is different
