Upgrade dive light to LED

[Defofthecrown]

I have been using an incandescent Ikelite PCm for a few years. I just got a 2nd generation Ikelite PCa LED and it is great. The LED is much brighter and whiter. I'm wishing I had changed sooner.

I'd still like to use the PCm as a backup, but wanted to switch the bulb out for an LED cluster. Does anyone one know what the most powerful, resonably priced, option would be. I tried to do a little reasearch, but am still unsure. I found some option that are 140 lumens that fit a PR base and jsut 'drop in', but they are lister for 4 C or D cell lights. Will those work with AA, or just ry the electronics?
