PL09Q is great.
Build and finish is good for the price
Optics are great compromise between throw and flood, it's more throwy than D4V2 with dedomed 519a.
FFL351A is phenomenal, rosy but not too much CCT is slightly below 4000K, overall very pleasant beam and tint.
Only downside is that button is a bit mushy.
Great beam profile, tint and cct.
I really like this LED. I have it in my T9R and also installed it in another light. Based on 3rd party testing, its not as efficient as the SFT40 3000k, but considering the smaller LES, this is expected. The LED outhrows the SFT40 by a noticeable amount. It has a wonderful tint. I hope they make it in a 3535 footprint as well so we can install it in our multi emitter lights.
I have quite a collection of various brands, beams, and emitters. The Firefly E07x Canon is at the top when it comes to power, efficiency, and features. My version (519a, 5000K) emits a broad hotspot that seamlessly melts into spill. I’d say more of a flooder with decent reach. Build quality is excellent too!
