T5-12TUBE-NW Natural White 12" T-5 LED Tube Light 4500k T5

Not quite as easy as the 18" models, use rvgeeks YouTube videos if you have problems. Once sorted out they are better than the originals.

I used these to retrofit the 12" florescent tube lights in my FourWheel Hawk pop-up camper. Pro's: They draw less than 50% of the power required of the fluorescent tubes. They start immediately in all weather conditions where the florescents are very slow in cold weather. They put out more light than the florescent. Con's: The drivers that come with the bulbs interfered with all radio stations received by my AM/FM tuner in my camper. I then ordered the low noise drivers and that helped a lot. I still lose low power FM stations with the low noise drivers. The stock florescent bulbs had no impact on my radio. The natural white light is a tad harsh on my eyes. They are quite bright. I'd probably order the warm light bulbs if I were doing this again. Overall I am satisfied with this conversion. I'd give it 5 stars if not for my radio issues. Understand that my camper is very small and my internal hidden antenna is located within about 4' of the light fixtures. I'm guessing most applications would not have a problem, especially if using the low noise drivers. One added comment - it would be nice if M4 would provide an option to purchase the bulbs with either the standard or low noise drivers. If you have the space, I would always opt for the low noise driver just to be safe.

Easy to install. Be sure to read the instructions! Very nice light output and color of light.

This was our second purchase of these bulbs. We are refitting our motorcoach with LED lights. My husband is installing and has done a dozen bulbs now. The first time he called the service tech at M4 and found them very helpful. Now he has a system, sets them all up and then installs them all. We love the light. So much better than the dull old flourescent. The kits have everything you need and we consider them a great buy.

Works great and looks much brighter than the old floresents we replaced M4 Note: YouTube

Still have not received the product. M4 Note: We received the order June 2 and shipped it June 2nd. The customer choose First Class shipping and he is all the way across these great states. The post office is quoting an extra couple of days for all mail packages due to Covid, and this shipped right in the middle of the Riots so trucks were delayed in LA and across the country. The customer never contacted us, but posted this review 6 days after shipment. Since this time, we have worked with the post office and the package was delivered in 8 shipping days total time. Folks, we can't control everything going on out there right now, but if we could I assure you the world would be a better place! If you ever have a question on a product, installation, shipping, or even the state of the world, try calling or email us, I am sure we will respond. Onward.

This is an outstanding product and I would give it an unqualified 5 star rating except for the tv interference on a few channels with weak signals. I note that there is a new module to fix this, but since I have more than ten of these already installed retro fitting the module would be a bit pricey.

to install correctly take time but product worth it.

The installation is a bit more cumbersome than the lights with a pigtail from the bulb, but once done it is a cleaner installation. I've had M4 products for years and they've been trouble-free.
