120V LED Under Cabinet Lighting

Hello everyone.
I recently purchased a new home, of which has some nice Under cabinet lighting.

But they are extremely hot when I use them. Heat = wasted energy right? I want to be as Green as possible in my new home. The problem is, the Bulbs are these weird straight 120V Bulbs from Westek.

So, the question is, Can I some how make an LED replacement Bulb? Each housing has 2 of these bulbs, and I have 4 of the housings.

I can't read schematics, but any info would rock.

Thanks everyone.
