Thanks for all those great measurements Maukka.
You’re lucky I don’t live near your place, otherwise I’ll knock your door with a big box full of TIR optics. I have approximately 80 different sizes and types of TIR optics.)
2000K and 3000K don’t suffer discoloration from OEM optic as bad as the rest of the cooler CCTs. Paired with 6500K there’s a sharp green halo. I installed the OEM to make packing easier. It’s easy to mislook between Jetusolis and JetuE21A.
Your graph shows how TIR optics gives us better control over the beam angle. OEM and 30° (the one with recessed hole) optic designed very similar to reflector, controls only the high angle light emission and let the central emissions exit free as wide spill. 10° and 20° optics collimate all light emission better to make combined total tighter beam angle with less waste spill.
