Can someone link a guide or discussion about CRI and RA? I’ve discovered today that 9080 isn’t the led name but the color rendering, now want to delve deeper
The 519A has slightly smaller die size and higher R9 compared to LH351D, so I would expect the output+peak current to be somewhat less. But I would welcome a nice surprise if future testing indicates otherwise!
My 90CRI 219C's have no issues with the 5A driver, unless efficiency is a concern. The 519A has around double the 219C die size and should have no issues with 5A. Unless there are some unexpected abnormalities like with the 219F, where the glass dome cracked at 4A.
Although the KD 219B 4500Ks are good, I’m not that impressed whenever I use the flashlight compared to my other 4500K flashlights. I guess I need a little rosiness in my tint. And I should’ve know better since the KD LEDs have a D240 flux bin which is pretty high. Good for lumens, but not good for tint.
By the way we have a group shipping with Clemence/Eurekatronix going on to save on shipping fees, we need to reach 100pcs per CCT for him to make the order, all CCTs available in 9080 3 step, price is 1.64$ per LED. EU, US and CA groups.
Note that the one from Convoy is sm455 (5 step), and more expensive.
If anybody is interested you can send him an email (it’s on his store front page)
