921-30-2835-CW Cool White Economy 2835 SMD Light Bulb with Wedge Base

Awesome retrofit for my 26' travel trailer. Replaced all incandescent bulbs for around $100. Lights are now brighter and use about 15% of the power and don't put off as much heat!

I spent some time reviewing alll the differetn light options and super happy with my selection. These lights pack a large amount of brightness without draining the battery. When plugged in I can have all 20 lights on in the trailer and the convertor does not even start, where two light fixtures would start the humming with the old bulbs

Well the bulb is exactly as advertised so I can't really complain. So I will just give my opinion. The amount of light is great but I dont like blue looking bulbs but I didn't see this type in a Natural white or Warm White. This was for my RV step light and is under an amber cover which helps some. The light is still too harsh for my taste. M4 Note: The Economy bulb is only available in Cool White as Cool white gives more visible light for this bulb since it uses a smaller chip. Always refer to our Color Range Page information and photos. Some love Cool White, some do not.

Great bright cool white, gives bright light in our closets and bathroom. The bases were a little to thick for the old light fixtures in our 2007 fifth wheel. I just shaved them with a pocket knife until they fit and they work great.

This is a great company they are so helpful they have a great product if you need light bulbs this is the place to get them that is LED bulbs

These bulbs put out 2x the light . I have my trailer at a non electric camp ground they work great with my battery bank and solar, usig 1/3 the power of reg. bulbs M4 Note: As long as your original bulb is a 912 or 921, they will use 1/9th the power.

Our interior lighting throughout our 2014 Surveyor was not as bright so, I searched the web on LED bulbs for RV's. I did some research and read reviews on other customers that purchased LED's for their trailer and was impressed by Chris Cutress review. After reading his review I looked at the 921-30-3528-CW Cool White Economy 3528 SMD light bulb with wedge base. It had 30 brighter lights and the convienced me. Installed the bulbs and sure lit up the trailer like having cool white florescent bulbs. Wife and I are really happy on the purchase and ready for a brighter RVing. No problems on the bulbs and fast delivery. Thanks M4

As a first time user I am impressed with the amount of light these things put out. As a dry camper I also like the small amount of power they comsume. I also very much like the speed of delivery and the customer service of M4led. Thanks guys.

When I bought out new trailer I felt that the interior lighting was not as bright as I would like it. I contacted M4 and purchased 10 each of the 921-24-5050-WW Warm White 5050 SMD Light Bulb with Wedge Base and the 921-30-3528-CW Cool White Economy 3528 SMD Light Bulb with Wedge Base. When they arrived I anxiously pulled out the factory bulbs and replaced them with the Cool Whites through the centre of the trailer and the Warm Whites over the beds, table, slide out, and stove. They made all the difference in the world and now I can turn on the Cool Whites and immediately have clear vision throughout the trailer with the option of turning them off and going with the Warm Whites in the evening for relaxation time. Great products at a great price. On little thing ... one of the Cool Whites didn't work when it arrived. I contacted M4 and they immediately sent me a replacement. Top notch customer service.
