Lightest green pointer?

[Tech^Cellfish]

I would very much like to buy a ~5mW green laser for a project, but I need the lightest possible unit. I know that most mobile lasers rank in at ~225 grams. Could some of you please give me the weight for your smaller/weaker pointers? Thanks a lot

(Please post weight without batteries, as I already have a 3V power source)

Without batteries or tailcap, my keychain green laser pointer (output ~5.5mW) weighs approximately 27g (just under 1oz).
I used a Pelouze postal scale that is not marked in grams; it weighs just under one ounce. That's where I came up with the 27 grams value.

If using batteries, use either button cell lithiums or energizer e2 AA/AAA lithium cells (L91). These are perhaps the lightest power sources you'll find.

How do you like the keychain green laser? I was admiring one on eBay.

As a laser pointer, I think it is as good as any of the pen-style units; though when carried on a keyring with a lot of jingling keys, both ends might have a tendency to unscrew themselves. It's nothing a little piece of tape won't rectify, but I should not have to use tape to prevent parts from falling off.

Thanks for the responses. I'll try to look one up on eBay. 27 grams is acceptable for my use :)

Will be my first laser. I want a high powered one too as I've always been amazed over lasers, lifters and railguns etc, but never afforded to play around with it until now.
