1. Current Draw: 1.35A
2. Run Time: 10 hours+
3. Optics: NX05 (I tried NX01, it produces a very nice and even spot but a lot bigger.)
4. Heat Issue: Use Artic Silver, the heat sink is big enough for 1w. I left it on last night for 8 hours, seems no problem.
5. The base: Just remove the bulb and drop in, the central pole is +ve, the heat sink is negative. In between the pole and the heat sink is a layer of clear epoxy.
