FYI, I have just recently found the "Revolution 200" from Starlights Inc. to be MUCH BRIGHTER than any other LED light I have been able to find. They work excellent as replacement bulbs in the RV overhead dome lights because they point ALL the light down when installed sideways in a ceiling light!
I found reading specifications of LED lights
pays off, because many manufactuers don't specify the Lumens (brightness measurement) of their LED bulbs - just marketing words like SUPER bright, Ultra Bright, etc.
I see StarLights now offers a 300Lumen version. I have used the 200L and 150L.
Revolution 200 LED - Star Lights, Inc.
I don't think they sell directly to the public, but several local RV dealers seem to carry them. (Pricey).
