Haven’t used product yet except for test. Worked well. Past good experience w M4 prompted me to reorder. Great delivery time.
We love this bulb in our RV! We changed half out last year, and decided to replace the rest this year. They are nice and bright, yet warm in color. They use much less battery energy when dry camping.....now we feel like we can use more then one light at time!
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.
