Amazing products
I have had many purchases from M4 and they have been wonderful to work with; I made some mistakes on size and they have handled each exchange fast and easy. The products are made very well and I can see why others have suggested them for LED's. Will continue to work with them and refer all to them.

Nice Color
Bought these for my 5th wheel and like the bright soft color
-
old trailer updated light bulbs
Excellent light output fit right in old incandescent holder unbelievable heat output between the two

Needed to reduce heat and energy consumption
Replacing all of the lights in my travel trailer made a enormous difference in the temperature during the summer and not draining my two 12 volt batteries. One more benefit to LEDs is, bugs are not attracted to them like the regular light bulbs. Very much worth the investment.

Clean and Bright
If there is such, these cool white provide the cleanest light (LED). I had LEDs in my travel trailer for they were more of natural light. I have installed these throughout the main overhead lights. What a difference these have made so far. I am very impressed and glad I have made the switch over to M4 LEDs. I plan on replacing all of my lights now, 8 to go.

great lights
Replaced all my light bulbs in my 5th wheel, what a difference. I don't need to have as many lights on and saves on my electric bill

Great little lights
We have replaced the lights in our closets, over the cooking area, in the bathroom and everywhere we wanted more light including our fifth wheel basement, over our entry door and the work light on the front of the camper. We are very pleased and pleasantly surprised with their performance. We highly recommend these LED lights to everyone who wants more light and energy savings.

921 Replacement
This bulb is just as advertised. The color is the cool white vs the warm bright color of the original incandescent. I am using these over the sink and prep counter in my trailer.

Great L.E.D. bulbs
Replaced all of the interior filament bulbs in my RV with the Cool White economy wedge base bulbs. Hands down better lighting. Brighter than the factory bulbs, brilliant bright white light. Made the interior much more alive. And they run cooler than the filament bulbs. Couldn't have made a better choice. And the service was excellent. I will do business with this company again.
