For "display" purposely only though I wouldn't suggest a Light, (as stated they do offer heat increase) you could go to a local hardware shop and pick up a LED strip.. and the nice thing about them is you can change color for day time/night tiem viewing from White to Red to blue to hell green if you'd like! and they are much cheaper and last forever (ebay can get like 50ft with the ballast and remote to change color) for 12$
