--------------------------------------

We have received hundreds of emails asking for a light which uses a 14500 cell battery.  We now have the ReyLight AA/14500 light which works with both cell variants. 

Also works with Maratac® Tasklight

Why use a 14500 Lithium cell? Higher voltage = Much brighter & also rechargeable
