SO! I have recently ordered from sci-fi lasers (100mw 520nm) and need help finding some reliable eye protection and batteries. I need some 16340 batteries but could i use Duracell 123's? or other brands sold in the UK such as Panasonic?

or
Ultrafire 16340 3.6V Batteries (4-pack) - Free Shipping - DealExtreme
or other recommendations please!

So moving on to eye protection!

I have heard Eagle Pair are great but could I go cheaper and still as reliable?

Thanks for your time! :thanks:
