Has anyone modded a lantern with these 9080 emitters? Seems like a good use for high cri good tint. This one here can change from WW to CW. I’m imagining 2000k or 3000k WW with 5000k or 6500k CW 9080.
Not yet. Just got quad dtp stars that I was gonna use to refit an old-timey-looking lantern. Probably will stick in some 351Bs (3000K) for now, which should look nice.
I don’t think it will create any artefacts at all. Didn’t make it in unique rotation because the dual dies in each emitter are too wide apart to each other and already asymmetric.
If in any case there’s artefacts at all, then frosted TIR should cure it easily. It fits all Carclo 106xx
Clemence, if you have a next order from Nichia, could you ask for some 219D samples? Or did you already have some (can’t remember). I really wonder why the 219D exists while none of the specs are significantly different from the 219C. Or are they simply cheaper?
I’m really hoping that this is not another typo. If this is the case then dedoming this LED would be the easiest and cleanest dedoming job with less lumen loss as usual. The idea of using multi refractive index material was introduced three years ago by a chinese scientist. He demonstrated more than 21% output using the same die. He used 5 layers silicone from the high to low to slowly reduce the RI transition to extract more photons off the die.
