What lighting to use for 10 and 20 gal terrariums?

[zrescoe]

Hello there,

I'm in the process of putting together two terrariums, one 10 gal (20x10x12) and the other a 20 gal (24X12X16); I purchased conversion kits from junglebox.net, so these will be placed on their sides. I hope to keep intermediate temp miniature Pleuros, so I would prefer light fixtures for the terrariums that don't heat up too much (if possible).

I am not at all knowledgable about lighting, wattage, foot candles, etc, thus any suggestions and tips are very much appreciated.

Thanks everyone!
