Great light
My entire rv is lit with LED lights. (I am a fulltimer.) One of the bulbs in the living room was defective, so I ordered the 921 wedge-base from here. The light is wonderful. It's bright, cool to the touch, and the delivery was fast. I am very pleased with the prices and service from M4 Products and will recommend them to my fellow rvers.

High quality for a great price.
I had purchased some LED lamps for my RV from a different source and was not impressed. Them I got some information about M4's product and what a difference. I would recommend these to who ever has a need for there RV. Vary good product.

Range Hood Light Replacement
I bought this light to replace the incandescent bulb in our RV range hood. The color and lumen output are perfect for that application.

The Best LEDs on the market
Never had an issue with the LED I have purchase from M4. The light output is the best I have seen. Did have one burn out last week and just one call they had a replacement coming, no issue or questions.

RV ceiling lights
50% brighter in RV with very little amperage, love them!

Most Effective I've found yet
Replaced bulbs in Kitchen with cool white bulbs. Easy replacement, plugged right in. Nice and bright, good even light. (Wife hates them, says light is too bright, but it's my kitchen) Will continue replacement of bulbs in overhead lights switching to the warm white to keep peace in the house. We bought the "cheaper" bulbs (9.95) but they perform better than the bulbs purchased at Camping World

Great service
It's so refreshing to talk to someone who cares. Instead of just sending product that might work we worked together to find the correct light for the application.

Very bright
Can't believe the difference between these bulbs and the regular 12 volt. Use them in my yard lights and motorhome. Will use them always, even though they are a little spendy initially, they last forever.

great fit, white light
Light is a white lite not so glaring as the original bulbs. Fit good and not hot like original.
