[mrsocks]

Hello,

got this light : http://www.dorcy.com/products.aspx?p=414279
Very impressed with the throw and flood. says 25 hours runtime on 3 AAAs.

Anyone know how to find out if i can use Li-Ion rechargables on this? I'm trying to find some specs on the imput voltage allowable on this.

I looked on the web site but it doiesnt inlcude that info.

Thanks.
