Have been using these retrofit LEDs for over 5 years. No failures, good color temp. They have a newer design now but I think that both use a heatsink / board combo with LEDs mounted right on it. They also offer a dimmer. Good stuff but maybe 30 bucks each.

There is nothing about the high output LEDs (like the Luxeon and others) that make them more or less suitable to use with a dropping resistor than the 5mm and 10mm variety. For running them at their maximum current ratings and light output, you really should use a constant current driver circuit for them - something you see in the more expensive LED modules. However, if you are willing to underdrive them, an appropriately sized dropping resistor solution is just fine.

I sent a note to my contact at LED Supply about the Luxeon Altilon bulbs. They would be GREAT for spreader lights...

sorry my bad I do have the anchor brand not dr.led.

My only use for the Luxeons is for my spot/flood and other high illumination projects like my fishing lights. I can buy and assemble the parts of most underwater high intensity fishing lights for a quarter of the cost of prefab. I like nice toys that I can build cheaper than buy it. All else, such as cabin lighting will be custom; LED ropes and "bars". Also, a little power regulation which would prevent trashing LEDs....

Oh and BTW......
