  1. Great LED Bulb 5 Star Review

    Posted by on 28th May 2015

    I bought 3 different bulbs to try before I bought this one.
    This one had the best white light output by far.
    Construction was the best of all.
    Bought 15 more to put in all my RV lights

  2. These lights are awesome! 5 Star Review

    Posted by on 27th May 2015

    The LEDs that I purchased from you have cut my electrical consumption by 2/3rds. The lights are perfect for reading in our travel trailer.

  3. Great Replacement Bulbs for Motorhome 5 Star Review

    Posted by on 15th May 2015

    I bought these a while back and was waiting to see how they would work. Well they are great replacements for the 921 bulb. I bought eight to replace the bulbs over the sink and over two chairs. My wife reads paper books and on her ipad. She loves these LED bulbs since they don't glare on the books or the ipad. The same goes for my laptop. I will be buying additional bulbs to change out the entire coach.
    Get the LED bulbs, you won't be disappointed with the bulbs or the service from M4.

  6. 921 Replacement 5 Star Review

    Posted by on 18th Mar 2015

    Replaced all 921 bulbs in trailer to LED. What a difference in the light that is produced and no heat. The reduced amp draw will also help the battery. I want to personally thank M4Products for fast service, fast delivery, and a great price. Quality is top notch... Keep up the good work. Highly Recommend...

  7. The best bulbs for the money 5 Star Review

    Posted by on 5th Feb 2015

    Extremely happy with the product, have replace about 50% of the lights in my RV will be replacing the remainder very soon

  8. Upgrade interior lights to LED 5 Star Review

    Posted by on 4th Feb 2015

    I ordered warm lights for general overhead and cool lights for work areas. They look great! The cooler white light are very bright and will work great for reading while the warmer lights are easy on the eye for general lighting. I can't wait for the season to come around to dry camp and test the battery life. The converter charger doesn't run as much....very nice. I did have one of the CW 5050 bulbs start blinking right after install. Emailed M4 and they sent a replacement ASAP...no questions asked. It is pleasure to deal with a company that stands behind their product. Will be replacing running lights very soon. Thanks Guys!

  9. Great light 5 Star Review

    Posted by on 3rd Feb 2015

    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.

  10. High quality for a great price. 5 Star Review

    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.
