Just ran across some beamshots of a couple Firefly E90’s with 909MX on reddit HERE, and I’m surprised by the nasty ring artifacts. I am no expert but my 4 lights with single large TIR (X1Lx2, Convoy M21H, IF22a) have the nicest and smoothest hotspot in comparison to my reflector lights.

And smooth hotspot is what I thought to be expected of single large TIR optic. Explanation anyone?

I can fix it ….

Thanks Boaz. I am sure with your experience & access to the many different diffusing films you have, DC-Fix and others, the beam could be fixed. I was posting mainly to ask why these large-TIR lights have such prominent ring artifacts vs my (smaller) TIR lights, which are more or less butter smooth.

My smaller TIR lights have the “classic” TIR beam shape: one smooth large round hotspot + faint spill that fades away smoothly, without sharp cutoff. Like the small TIR lights Firefly X1L & E04 and Sofirn IF22a below.

[Review] - Fireflylite T9R vs Wurkkos TS30S Pro

I’m sorry, this review was actually done months ago but was never published… Let’s have a look at the Fireflylite T9R, featuring the FFL909MX@6500K emitter and using the Lume1 6 amps + FET driver. Purchased in January 2025, it is my second Fireflylite and second dedicated thrower. I will compare the light with a Wurkkos TS30S Pro (SBT90.2@5700K).
