I wish all upgrades were as easy as these tube lights are to install. Males the interior much brighter. Will continue to pay products from M4.

Over the last year I've change out all of the ceiling lights in our motorhome to LED from M4. The LED bulbs are so much brighter than the old flourescent ones and use much less power. The power use is very noticeable when we are dry camping. With the fluorescent bulbs, you could almost see the battery draining (well, not really but you know what I mean). The LED ones just sip power. The product is very well made and it easy to install if you have basic electrical skills. Can you find cheaper ones? Yes, but you get what you pay for. The cost differential between the cheaper ones and the M4 is minimal and offset by the great customer service of M4. I have recommended M4 to many of my friends looking to upgrade to LED. Bottom line is you'll be happy with purchasing from M4.

Purchased 8 of these bulbs to replace Flouresents. All work great. I have had in RV for 2 years. I have had one bulb in one fixture that occasionally flickers on and off. I have twisted on the bulb and it goes away. I most recently purchased another replacement bulb, but have not used it as during the last 2 months of use, the original bulb has not flickered any. Excellent product and love the Naural lite (5K) M4 Note: It sounds like it was just a little loose in the fixture. When putting T8 tubes in, be sure to hold the end caps when installing because the tube has rotatable end caps. Ensure the pins are where the should be in the fixture sockets.

My RV coach was wired from the factory with four dual florescent fixtures for a total eight 18" tubes wires in series on one switch. Lucky for me the fixture also have a switch to turn off each fixture individually. As the ballast worn on 9 year old coach I couldn't switch on more than two at a time. Wiring the LED tubes was easy as 12v at one end of tubes and ground at the other. The color of the light is right for my taste as I know now that the cw would be too white for me. Now when I turn on the wall switch all eight tubes come on instantly. The one problem I encounter is that since these are wired on one switch is that one tube may turn off and on occasionally if six or more tubes are on. I checked the voltage to them and even though the fixtures are getting 13.7 volts it still dose it. Somehow I think the RV coach should had been wired using more heavy wiring using four fixtures on one switch. There is no other problems with other fixtures in the RV coach as there are many. I did get a extra pair of tubes and think the rear bedroom will be a good place for them. The jury is out about energy savings compare to florescent but the do come on instantly because they have their built in drivers. I would like to see cost come down to make sense of return on investment. M4 Note: There is no reason for one to flash when all are on. Please recheck your wiring and ensure all wire nuts are tight. They fixtures won't/can't be in series, they are in parallel so they should all get equal power.

Put these in over the kitchen sink. I thought the original bulbs were bright, these are brighter. Bonus, they draw less power. The color matched the old bulbs perfectly. Liked being able to aim the tube by having the rotating ends. Nice thought. Being an electrician, the fixture rewire was a snap. But just about anybody can do this.

Our fifth wheel is seven years old and a few of the ballasts in the fluorescent lights have been failing. We have replaced the entire fixture. The LED tube lights eliminates the ballasts and the rewire is simple with the included instructions. When the light is on you cannot see the individual LED's inside the bulbs that is fantastic. The 2 bulbs cost less than the fixture and we like them so much we will be replacing all our fluorescent bulbs with the LED tubes in the near future.

Purchased six replacement tubes. The conversion was simple and the light output and and quality are great!

The 18' LED Tube lights arrived in only a couple days. Customer assistance via e-mail was very quick to answer questions about application. It was extremely easy to figure out the positive and negative wires and still keep the switch on the light fixture itself. The lights are fantastic. I ordered the cool white and it outshined the other fluorescent fixtures. I'd recommend these tubes to others even though they are a little pricy. They are well worth the money spent and saves tons of energy in the long run.
