      Excellent product!

      Posted by John T on 8th Mar 2023

      Replaced the 18” fluorescent tubes in our bathroom ceiling fixture with these LED tubes and WOW!! First and foremost the retrofit is super easy using the included instructions and the RV Geeks videos. The light output is far superior to the old fluorescent tubes and the dramatic reduction in power usage is huge. Time will tell on their longevity but M4 products have always been very high quality. Highly recommend this upgrade!!

      Motorhome led tube lights

      Posted by Steve Feenstra on 4th Mar 2022

      The new led tubes really make the motorhome lighting nicer. Much brighter but not glare in your eyes. Install went great with removing all old ballasts.
