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

At first I was not sure if this was going to be complicated and hard, then I saw the utube. Really simple and easy to follow instructions. Works great and looks just like the original. Can't wait to Try out boondocking in Big Bend. Will be looking at replacing other fixtures after our test in Big Bend.

My fixtures have a double tube so I had to jump the two end contacts together as well as eliminate the old ballast and control circuitry. I ended up taking the contacts apart to remove the old wires rather than just cut them. The ballast was pop-riveted in so I just left it in place. It took a little manipulating to get the bulb heat sink in the right position so when you rotate the bulb, it ends up on top. The light is so much brighter and natural and got rid of that yellowish cast altogether. Would highly recommend switching to these LED bulbs.

We followed the instructions for the 18-inch, T8 tube light, and it was easy to install with attention to safety precautions (disconnect circuit first) and attention to every detail. It's truly a more natural light than the flourescent that it replaced, and it is brighter. Colors under the light look more normal and accurate. Impressive! We installed the Dimmer-N as a surface mount device right next to the light fixture, and it works fine. Next, we'll order some chokes from Digikey and put a choke on the incoming cable from the ceiling to cut noise from the LED driver circuit along with chokes on other devices here (inverter, controller and other aplliances that already generate noise through the 12-volt lines)--some work that needed to be done here anyway. We're happy with the 18-inch, T8 tube light and will order more as soon as possible.

Just replaced our second RV lighting with these and am very satisfied. Easy to replace and love that you don't have the wires hanging off of the tube. To be able to run your lights with half of the wattage is worth it's wait in gold in the RV industry when you use mostly battery power.

We hake been changing over all our RV lites to led from M4 and have just been very happy with all. The replacement fluorescent bulbs are the same natural lite,but definenitly brighter and sad to say almost as hot as the old bulbs. I do like them and will use them for sure,they don't make the inverter kick on,just don't like the heat. By the way all the other LED lites stay cool to luke warm. M4 Note: On a florescent tube, the heat is focused more at the ballast. The LED has a heat sink along the back of the tube for long life, so the heat is drawn from the LED chips themselves, so if you touch around the aluminum heat sink the heat will be concentrated there. It will not be too hot to touch, and really shouldn't be any hotter outside the fixture than the florescent tube is.

I purchased six of these conversion LED's to refit existing fluorescent tubes in my motor home after reading the high praise on howtorvgeeks.com. Installation was very straight forward. After installing the first pair, the next two pairs took less than ten minutes to complete. Now? No more flicker on start-up and the light quality is better than the harsh light we had from the stock tubes. This upgrade is a must have item!

These T8 replacement LEDs are awesome. My only concern before I ordered them was the note in the description that stated that the length not including the pins is 17 1/4" and if your fixture does not have that much clearance they may not fit. I called M4 and the customer service rep I spoke with went to the warehouse and actually measured one and told me it was actually a little less than 17 3/16" and it should fit. I ordered 2 of them and they fit with room to spare. Rewiring my fixture was a breeze and I had the project complete in less than 20 minutes. The light output is great and I really like the natural light color. I highly recommend these as replacement LEDs for your fluorescents.

No problem using the instructions, very, very easy. However the instructions that I got off the Web were much better than those that came with the led tubes, there was photos of all of the procedures. Only took about 1/2 hour to install both bulbs. Makes all the other lites in the motor home look dim. If & when they quit I'll surely order more of your units. Now waiting to see just how long they last. Thanks, Don M4 NOTES: In an effort to save a few trees, our packed instructions have a diagram and written instructions and less pictures. On those instructions is a link to get the same instructions, but with many more pictures. That link is http://m4sales.com/tubelightinstructions/

I just switched the LED fixture out in my camper after the incandescent switch over went so well. It was a little scary when I pulled the cover and started re wiring to put in the LED tubes. It all went fine after I read the instructions and in about half an hour I had it done. The light was great! We liked it so well that I switched out the second fixture in maybe 10 minutes, went to the computer and ordered the second set of tubes! Until then I am running one tube in each fixture and even with one, the light is great! Two makes the counter work space awsome! The instructions are thorough enough to get the job done by most folks with basic wiring experience.
