> I'm looking to buy a Preon 2 w/Nichia 219
I do not recommend lights that use Pulses, such as the Preon
here are a couple single AAA and single AA suggestions, for non pulsed lights with Nichia LED.
I recommend the Copper Lumintop Tool with Nichia. Mode sequence is M-L-H of 18-3-80
since it starts on medium, I consider it very practical for office use where there is not full darkness
I have a couple for sale if you want the ReyLight version whose mode sequence is L-M-H of 1-18-80, PM me if interested, brand new in a sealed package. Starting on Low first is preferred by flashaholics, because it wont blind you on its first mode, if turned on in full darkness.
fwiw, there is also a Titanium version of the Lumintop Tool, also with Nichia. I do not recommend it as it is not germicidal and imo the flush switch button is harder to use. OTOH, a doctor is likely to really like Titanium, which stays clean and shiny looking, more than copper that gets tarnished and some people think it looks dirty.
Copper is antibacterial though, Titanium is not.
since you asked for a 2AAA light, and I dont know of any with no Pulses and High CRI, I recommend as an alternative, the L11c from L3 Illumination. It comes with a Nichia option in Aluminium, and uses a single AA battery. Mode sequence LMH of 3-30-140.. this is a really versatile light. imo the modes are very good for medical use. It has an excellent tailswitch also. Its slightly heavier than the Tool, but the pocket clip position of the L11c is far superior.
very kind of you to shop for a gift, I hope you find one your recipient likes
