I ordered from Marinebeam in 2015. I've been pleased. Below is my order. The G4 was for another boat. I have a Perko anchor light and used the Cool White for it. Very bright. I returned the Warm White.
I can have the LED anchor light plus another LED light on inside and draw less amps than one incandescent original bulb did.
I really do like the switchable white/red. I put one over the table. Makes it bright enough to see inside but you can still look out over the anchorage. The other one is in the Head. Nice to have a light in there and it doesn't wake the spouse up. If one of the plain white ones goes out I will replace with the red/white.
I need to order some LED for the cockpit courtesy lights. I keep forgetting to look at the size.
