Reactor guts

[Burnt_Retinas]

Having bought a Reactor flashlight, I promptly went about destroying it...

The Guts:

The P1 rated LSLD:

The Reactor is direct driving the LED and no additional heatsinking is provided. It’s as cheap as it gets.

My opinion of the Reactor – it’s junk. Only worth pulling apart for $15 of fun.

P1J actually isn't such a bad LED. How did you get the Reactor open? It looks like you sawed it in half.

Does the LED get hot if you run it on two AA lithiums?

 

[Burnt_Retinas]

The head is 2 halves held together with a metal ring at the front (glued) and a clipped on plastic ring at the base. The plastic ring can be removed, but the metal ring is so well glued you have to pull the 2 head halves apart until it breaks at the metal ring.

I haven't tried lithiums. I did put a Li-Ion in and resistored it for 500mA though. It is the old common NX05/low dome combo. Combine that with the cheapness of the Reactor and an uncertain off position and it wasn't really worth keeping for serious use. I wasn't impressed with the light even at 500mA, and yes it probably ran hot but didn't feel it. I really didn't want to get too serious with this flashlight.

P1J ? is a good Luxeon ?

That thing should be greener than grass.

I'm glad I did go down the Reactor path from the very beginning! I believe they were one of the first commercial Luxeon I lights...

P1J would be yellowish but reasonably good flux-wise, I think.

Re LED color, you'd be surprised. Without NX05 it's green, but the NX05's refractive index properties seem to result in any blue being present to get focussed into the hotspot. It was quite white, with a blue tinge in the hotspot, but green elsewhere. I've seen this before with NX05.

It goes to say of course, than using other optics the "1" rated may look green.

Then I wonder what rank of LS ended up going in this Reactor:

Now that's "rotten cat urine green" if I ever saw it.

yeah Craig, but look in the center, it's not blue, it's white! /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/tongue.gif

Good ol LD technology.

Not sure about the original Reactor, but the Reactor3, I've been impressed with so far - though granted, it is my first LS based light. Nice white colour, no switch issues, and well bright (out shines a pretty decent 10 LED light easily), and the batteries seem to last well. There's a review of it on my website, got 76% if I remember rightly.
