I did some very casual testing of a few examples of some bulbs I got recently, mainly to see if they would handle 2x Li-ion. They did, at least for the brief period I had them on for. I used my Fivemega G4 bi-pin M@g adapter with both bulbs.
The Philips 7387 is a nominal 6 volt, 10w bulb. First it went into a 4-D cell M@g fueled by Dollar store alkaline, then into a 2-D ROP setup with 2x AW IMR 26650. I'm not going to guess at output. Projected 100 hour at 6v.
The Osram 64410 S is also a nominal 6 volt, 10w bulb. First it went into a 4-D cell M@g fueled by Dollar store alkaline, then into a 2-D ROP setup with 2x AW IMR 26650. I'm not going to guess at this output, either. Projected 2000 hour life at 6v.
If Lux Luthor wanted to test them, I would be happy to send some examples along.
The one annoying thing about the 64410 S is the gloopy tip that reminds me of a Dairy Queen soft-serve cone. It's not a complete loop, but there is enough of it that when using it in the 4-D with a light-orange-peel textured reflector that it left a shadow in the center part of the beam. It's particularly annoying because this bulb has an axial filament. The same problem was not present in the 2-D using Fivemega's "bi-focal" reflector. Has anyone ever removed excess glass tip material with a Dremel, or needle file?
