Hold on to what you know about lighting....it may all change and change very soon! This comes from a lighting company that custom makes these to order. I restate....they CUSTOM make these to your application. We had them made to replace parking lot lights.
This bulb is 30 LED's, has a mogul socket and self regulates to the input voltage from 110 thru 480. Just plug and go. The first three pictures shows the bulb. The next two shows the bulb at full power and then at power up. It measures only 10" long and is 4" round. Then the last two pics show the experiment tank...a 65 gallon. The bulb cost me $136 but it doesn't get much easier than this to install. Note that I'm holding the bulb in the tank pic. The maximum off temp is 130 degrees but that was in a fixture, fully enclosed with a glass lense. It's also a little yellow because I believe it to be around 6500K for output but again, this company can certainly make them at higher kelvin.
