The best LED's and fast shipping
These are by far the best LED bulbs I have purchased for my RV camper. I tried other LED's that were cheaper and they just didn't compare to the quality and brightness of the M4 Products. Shipping was very fast, received the bulbs in 2 days from CA to MN. THANK YOU!!

Great product and service
After seeing a YouTube video extolling this company's LED lights, I drove all the way to Chatsworth to buy some for my travel trailer. The owner of the company was very kind in helping me to decide which light style would work best for me. I am now traveling, and boy am I happy with these lights! If I have every light in my trailer on, it uses about as much of my battery power as one of the old incandescent lights. I'm a happy camper!

Very Happy
Same warm white as incandescent, maybe a little brighter. Left them on for over an hour - stayed cool. The 921's I replaced had melted two of the fixtures. HIGHLY RECOMMEND THESE M4 LED'S.

Excellent Choice
We found out about m4Products on YouTube. We ordered a couple LED's for our RV and were very pleased. Then we ordered enough to almost finish off replacing all the original bulbs with LED's. We will be ordering a few more shortly. Good product! Good customer service too!

Still Happy
After a small problem, it was quickly, and completely resolved. So happy with M4! 6 years of dealing with them.

so far so good
I've purchased over 40 bulbs in the past few years. The only small issue I have is the interference with the radio reception when using the bulbs on certain circuits. May be unavoidable with LEDs at this point in time. There was one bulb that broke while installing. The wire contact on the wedge base fell off. I'm going to return it and hope they make it right. I've been happy with M4, and believe they will fix this promptly.

light for rv kitchen
Great shipping, arrived quickly. This warm white wedge base led in a little more yellow than I expected. It does give much more light than the incandescent bulb that I replaced.
