Yes... where did you find that tiny little thing. Also, is the light next to the sparklite one of those Coast lights we were discussing recently in another thread? I didnt realize they were that small.
Yep, that's a Micro Lenser from coast. They're one of the US distributers of Zweibrueder.
The little LED can be found in the fishing section of Grandpas, WalMart, and other similar stores. They are designed to go in the clear fishing bobbers to light them up. You push down on the head a little and it turns on, pull it back out and it turns off. Pretty neat and takes up little room.
Both LED's actually use a very similar battery. The tiny one basically has the LED fuzed directly to the head of the battery, while the Micro Lenser's battery can be replaced. I found some spare batteries at batteries plus, but they weren't cheap (like $4 each). The battery is called BR435 (it's a 3 volt lithium). The micro lenser itself (with battery) cost me around $10.
Needless to say, while I like photons, these two are simply smaller! Well, the micro lenser is a little longer than a photon I think, but it's easier to pack since it's shape isn't so irregular
