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

The 18" florescent tube LED replacements are beautiful. The rewiring went well. Less amps and less heat, and a little more light. A little pricey but well worth it. My only concern is the solid wire included with the tubes. I don't like to wirenut small stranded wire to a stiff solid conductor so I used a piece of 16 gauge stranded. The bulbs are just great.

First, modifying the original florescent fixture was easy, but wire strippers were a big help. When I put two LED tubes in to replace the florescents, we were surprised at how bright they were -- too bright for the location, actually, so I modified a second fixture and went with one LED tube in each. That works fine and in replacing 4 tubes with two, we replaced 60W of florescents with 16W of LEDs! M4 Note: Typically the LED tube are about 10% more light per tube. Some people of course want less light. One tube per fixture works fine, but looking up at the fixture half lit can seem odd for some so we recommend two tubes. Natural White or Warm White color choices can also reduce the visual light.

Installation went well. The instructions are very comprehensive. The LED tubes give more light with less power and look great.

. . .GREAT when you want to reduce your energy ( make your batteries last longer ). . .Run your GenSet less . . . Cooler in the Summer. . .These are nicely made & light output is GREAT!. .. STUNNING service when you have questions!!! . .Man-O-Man, what is there not to like about this outfit & their products?!?!

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.
