I think the S21D is the most underrated light on the market. Almost no one hypes it. Only a handful of reviews for it (all positive). Once more of them are in people’s hands and folks are posting about them and reviewing them sales will take off.
Granted, I’m biased. I think they are awesome. Simon is sending me a sample of the new 12A driver to install in one, so I’m pretty excited. I’ll have a 8A 519a 5700k and 12A 519a 5700k to compare head to head, along with my current 219b & 519a 4500k models.
This is so relatable. I think about some purchases for weeks and the result is that opportunity sometimes passes me by. On the bright side, at least I’m saving money on some frivolous purchases.
Nope. It’s the 219B you don’t want to use with the 5A driver. The 519 can handle it just fine.
Djozz tested it, and the 519A peaks in brightness around 6A. So 5A is a nice max current. It’ll get hot in an S2 of course, but it won’t harm the emitter.
If you want to run high mode without extra heat the 3A driver fine too. But you’ll have to solder it to the pill, which is annoying.
I see, thank you for the inputs, I’ll get some of these 5A drivers.
By the way, I have a couple questions if you don’t mind
What driver Simon sells his 519a S2s with?
Just want to have an idea of the heat these will pump out, also, efficiency is a bigger concern to me than sheer output but if should they be the same, at the same brightness, I wouldn’t mind have a little extra oomph at all, I just wouldn’t like to sacrifice efficiency at the same middle brightness levels which is most of my use time.
What are the architectures Simon uses in these drivers, are they buck boost, linear, linear + fet…?
Hi Simon. The 17mm forward switch I got is a bit different from the one pictured. the switch has a black top instead of white top and the mcpcb has 1 center hole instead of 5 center holes which is exactly like the 16mm switch pcb. it measures just under 16mm like your 1288 16mm switches.
Is there a way to get LEDs cheaper?
If you get 10 pcs the price is $2-3 but I want to try various LEDs and tints.
You have to buy per piece and 519a for instance is $7.50 for one. If you buy multiple the price doesn’t decrease.
