I still have some SMJLED PR2 drop-ins (courtesy of Lambda, many years ago - where is that guy these days btw?), and for long-running on 2-cell lights of varying stripes and sizes, it's still pretty neat. Long-running, bright enough for most general uses, and easily swappable between hosts.
Was just curious if other PR2 based options were out there, since I remember Lambda had a hard time even getting the SMJLEDs potted into the PR2 housing, and came across this:
They have a few, and the two more powerful ones are:
PR2-3WHP-x: 3 Watt Flashlight Bulb - $14.95
PR2-1WHP: 1 Watt Flashlight Bulb - $10.95
Kind of pricey in one sense, since in some places you can get a 2D MagLED for $15. But still, it'd be a nice way to breathe life into a 2-cell PR2 light you have that you like for sentimental value, you don't want to add to a landfill, etc.
Has anyone used any of these, any experience with them?
There's also a .5 watt (I think that means either SMJLED-type, or Chinese-made lower power LED) version for $5 and change too. Might be super-long-running.
