sMJLED-PR2 bulb
I got a couple of these from TrueBlue's special at $6.66 each.
and had been trying them out in some cheapo 2D and 2AA flashlights.
Last week I was in my local WalMart and came across these real cheapo 2D lights -
The economy Eveready was $1.68 including 2x Super Heavy Duty D batteries and economy Ray-O-Vac was 99cents without batteries.
Sizes -
The Eveready was shorter because of its shallower reflector and there is less hooding of the head.
Heads with sMJLED PR2 installed -
As can be seen the Everready seems to doing a good compromise of facetting the central area to smooth out any rings with then out part mirror finished to maximize the reflected light. Being pretty shallow not only make the light shorter - but it also means the side-spill/corona is pretty wide.
The Ray-O-Vac is a much deeper polished reflector.
sMJLED PR2 in Eveready vs. Ray-O-Vac
The Eveready side-spill is really wide - it easily over-lapped the Ray-O-Vac beam. Although I like wide side-spills for the level of this light it seems to dissipate the side-spill too much - so that the hotspot is much, much brighter than the rest of the beam. The central facetting does not seem to have been effective in avoiding the central donut hole - there is one on the Ray-O-Vac too - but it's only at closer distances - by 3.5feet they are gone.
These sMJLED PR2 in 2D lights are significantly brighter than any of the
MJLEDs or
sMJLEDs I have in 2AA MiniMags - they seemed brighter than most 1watt Luxeons I have - they are almost comparable to 3wtt Luxeons......
sMJLED PR2 in Ray-O-Vac 2D vs.
Fenix P1 (3w 1xCR123A primary) -
No, it's not quite as bright - but it is close and at least comparable and the throw is possibly better........
It's not a fluke......
sMJLED PR2 in Ray-O-Vac 2D vs.
Nuwai Q3 (3w 1xCR123A primary) -
Different beam characteristics - but close/comparable......
I'm impressed.
The sMJLED PR2 in the Eveready is different since the shallower reflector spreads the light out more -

sMJLED PR2 in Eveready 2D vs.
Nuwai Q3 (3w 1xCR123A primary) -
The sMJLED PR2 bulbs display the same blue tinted charateristics as my
sMJLEDs tested in 2AA MiniMags - the one I had in the Ray-O-Vac has a marginally better tint than the one in the Eveready - but it is really only noticable side-by-side.
