    Electronic noob wants to make underwater LED lights

    Calculator tells you how much needs to be dissipated. If you go lower, resistor will destroy it self.... Watt is an amount of energy that needs to dissipate ! Let's say you need a 10 Ohms/3 watts resistor. You could put 3 x 3.3 Ohms/1watt in series. Using many smaller resistors might be...

    Check on ebay: you can purchase 10w LED, that connect directly on 12v - no need for an extra resistor ! Also, you may want to check this site: www.smoothon.com . They sell resin, urethane & epoxy. One of their product is crystal clear & UV resistant.
