I would go for LED lighting. No Heat and very little problems with UV regarding leaving on all day you could do but personally I would buy a plug timer just for safety. Amazon do alot of kits for LED strip lighting for a tight budget and you can cut it to the size you require. It also allows you to change the color of lighting.
