Quality product, would order again without hesitation.
Love them I recommen them highley
These bulbs are perfect for our needs. They have all the power and heat advantages that make LED bulbs so popular in RVs with a very nice comfortable and pleasing light output.
We bother love natural color of the lights. Being able to boon dock at without any worries about killing the batteries.
M4 products is awesome and Steve is easy deal with. I get all my light from Steve.
Would highly recommend M4 Products.
We had fourteen 921 and 912 bulbs in our motorhome and these are perfect replacements for those incandescent wedge base bulbs. One caveat: these bulbs are longer/taller than 921/912 bulbs, so they may appear a bit obtrusive in downward-facing fixtures. We ended up exchanging four of these LED bulbs for a smaller version also carried by M4 that cost a bit more but look nicer when the entire bulb is visible (and are still very bright). Thanks to Steve for helping us out with the exchange.
While searching for LED bulbs for my RV I came across M4. Their company and products were highly recommended by several RV users and companys that sell RV products. Their website is very user friendly, informative, and made selecting LED replacement lights for my RV easy. Customer service is outstanding. They shipped my order the same day. The bulbs fit perfectly and look great. Thanks for being an outstanding American Company.
Decided to switch out the standard bulbs in our RV to LED bulbs. The difference is great on three points. Better lighting, way cooler than the standard bulb, and the use of battery power so lights can be left on longer. Don't have to rush to do something and then turn off a light.
Natural color, very bright and we can leave the lights on without worrying about draining the battery too quickly.
New to my RV, folks told me to get rid of the power hungry incandescent light bulbs in my RV and get some LED's. Everyone on the RV forums said to use m4products to get quality LED's. I bought 13 of the Warm White 5050 SMD light bulbs. Very quick shipping and well packaged. Bulbs arrived in perfect shape and are all installed. Very tight fit, you must be careful installing. Thanks m4products. Will do business again.
