Driver doesn't know how many leds you connect to its output,practical limitation is heat generated in driver;how to calculate that,you can find in info thread.
With LD-2 you can get practically identical current on max. like with DD drivers,check djozz' LD-2 prototype test and comparison of currents vs. DD driver. The important difference is that LD-2 will limit current when it reaches 6Amp. You can change 150k resistor if you want higher current,but with typical cree xm-l2,xp-l 6Amps is usually max. possible current with 1x cell (ok,maybe you could achieve 6.5-7Amps,but only for a few seconds,and gain is minimal).
led4power, I just wanted to be the first person to thank you for making this possible.
Prices are very fair imo. Someone like rmm or the others could get maybe 100 at a time and offer them to us for around the same price his other drivers are.
I absolutely loved the five LD-1 drivers I purchased off you before. I’m looking forward to trying these new LD-2 drivers. Your design looks impressive. Just trying to figure out how I can get five of those sweet drivers. I hope Richard of Mountain Electronics carries them as well. By the way, it is folks like you that make the BLF a very special place! Keep up the great work, cheers!
I offered already to do the US group buy if nobody else steps up. But, I’ve also been waiting to see if Richard will carry some of these in his store, because that would be much better. I think, if we end up going the GB route, we will need to reach 100+ drivers in order to get the best price, to cover re-shipping from the GB host (me, if nobody else does) to each individual purchaser. Maybe 50+ pieces would be enough for that. But, in case you missed it, the MOQ was reduced to 4 pieces for anyone outside the EU. That’s probably low enough for most people interested, although the price will be higher than what we can get with a 100+ GB.
Waiting to see how this shakes out for US buyers. Would want two to four depending on price. Hopefully, the price will show a modest discount from the qty. one price.
I’ll open a gb thread if necessary(led4power wants me to) otherwise I’ll just keep it here. This thread might get crowded so I opened a thread for a US GB.
I’d appreciate it if you could put me down for 2 for the US group buy. I wanted to get 6V parts for 1 of them - can we do that? or just plain drivers for this?
