Our local “Ollie’s Bargain Outlet” store has 2 15 inch strips of red LEDs For $7.98 and 2 10 inch strips for 4.98. I have installed a number of them in my germination refrigerators. They appear to be brighter than the Radio Shack “super bright” red LEDs that I was previously using. They are very convenient to install as they come with an adhesive on the back of the strip.
The company that manufactured them is “Electra” ( http://www.electrausa.com/Our_Product_Pages/Auto_lighting.htm ). The product is called “LED FLEX STRIPS”.
They require a 12 volt DC power supply as they were desighned for automotive “decoration” type use. Whenever I discard an electric appliance that uses a plug in power converter (house voltage to low voltage DC), I keep the power converter. So fortunately I had several that had 12 volt DC output.
I now germinate my seeds in two 1.7 cubic feet refrigerators of the “thermoelectric” type. I have 1 Avanti model EC15W-2 (purchased at K-Mart, see http://www.kmart.com/shc/s/p_10151_10104_9990000031676411P?vName=Appliances&cName=Refrigerators&sName=Compact+Refrigerators for a description) and 1 Galaxy model 183.91772 (purchased at Sears, the Sears one is supposedly a new model that is not listed on their web site). The 2 are very similar. The Sears model appears to be made by the same company as the Avanti. The Sears appears to have a slightly improved design compared to the Avanti.
