T8-18TUBE-NW (F15T8) Natural White 18" T8 LED Tube Light 12v 4500k T8-120-3528-18-NW

Someone recommended another company to me for the LED lights I needed. One phone call to this company where I was connected to someone who had no knowledge about their products, their spec's, etc. convinced me to go back to M4 where I knew I could talk to a knowledgeable individual and where I knew I would get an excellent product. And indeed I did. I talked directly to Steve who took the time to verify the product was in stock. The 18" fluorescent bulbs were promptly shipped and arrived when expected. They are of the highest quality and were very easy to install. The difference inside our coach is as they say "the difference between night and day". The lights provide a nice bright white light and the icing on the cake is that they are energy efficient. I will never again even think of going anywhere else but to M4 for LED products.

Ordered these 2 as a test. Found the directions were easy to follow and only took a few minutes to install. Will be ordering for the rest of the RV fixtures. The LED does away with the problem of the fluorescent lights not working until the RV temp above 45 degrees.

Not only do we have far better light with our new 18 inch LED tube lights but they solved a problem we had struggled with for several months. We have a 2002 Fleetwood Discovery and were having trouble with the control board for the furnaces and air conditioners locking out the thermostat and making them inoperable. As it turns out, ballasts on fluorescent lights can cause interference with signals from the thermostat to the control boards. If the fluorescent lights happened to be OFF everything worked well, but if one or the other of the two lights was ON, the thermostat would appear to malfunction. Luckily while watching a YouTube from RV Geeks we discovered M4 Products LED replacements lights. We ordered four 18 inch replacement LED tubes and installed them in the fluorescent fixtures. They were easy to install, bypassing the fluorescent ballast completely and made such an improvement in the light quality in our motorhome. We found the Natural White LED tubes are brighter than the fluorescent lights we replaced but they are not glaring. We liked the LED tube lights so much we have now replaced all of our other 12 volt bulbs with LEDs from M4 Products.

Purchased 4 lights for 2 fixtures. The instructions were clear and easy. My fixtures were riveted so it was necessary yo remove them from the coach drill the rivets to gain access to the ballast. The rewire was simple. 4 screws snap the bulbs in and install the original cover. The lights are bright but not crazy bright. Good value M4 Note: Most fixtures have ballast covers that pin off, or held in with screws. Some fixtures like this have rivets. At the top of the instructions is a link to our Resource Page which has alternative installations. One is this type of fixture and it can be rewired without removing the ballast if you pull the fixture down. It is hard to see, but do-able. Remove the rivets and replacing them with screws or rivets is also ok. See the resource page at m4sales.com

I replaced 8 - 18" and 2 - 12" flourecent tubes in just over an hour in my yacht. They were pachaged well and included very good instructions. I used the natural white andThe lighting is much improved and power consumption a third of the flourecent bulbs. Easy fix and highly recommended.

I'm currently converting all of my light fixtures to LED. I'd had a different product which came with a 'strip' light. The wires were so fine (22awg) that they were nearly impossible to work with. M4's 'tube' light eliminates all the hassle and makes the installation dead simple.

The lights are way brighter than the fluorescents. Easy to install. Only took about 10 minutes per light. I will definitely be changing out the rest of my lights.

Are they expensive? Yes, but they are worth it! There are no LED fixtures out there that will fit or conceal the outline of my current Fluorescent fixture. Since it is recessed I would have to make a lot of modifications or have an ugly hole. These fit the bill perfectly, changing the wiring was very easy, and in about 30 minutes I had it all back together. I love the brightness, I used these in the main kitchen area where I need good task lighting.

This is my second or third order from M4. Product quality and company customer service has always been excellent. Stumbled upon a 5 minute "How to Video, Part 3". This video convinced me to give the project -replacing 3 18" florescent ceiling lights with LED tube lights a try. I watched the video 3 times. Ordered the LED tubes from M4. They arrived 3 or 4 days after order placed. The new LED lights were installed in less than an hour. There is a night and day difference in the amount of light in the RV.
