Marine

Great , I have used the 3-5 watt 32v leds to replace the house bulbs on a 1989 Hatteras. An avenue to sell your lights could be through Sam’s Marine , they are everything Hatteras in south Florida

5w over the kitchen sink (10w was just too bright). Solar Powered.

Have used the 10w w.w. lamps for 3 years (ever since first introduced). I have been tickled with them! I used others, but they tore up my FM radio reception. I highly recommend! I have both 12 and 24 volt circuits in the house, powered by a roof top solar array. Love that the lamps can be used on either voltage. Our house has one main lighting circuit, which runs 120vac from the inverter. I've toyed with the idea of changing it to 24vdc, but have had to wait until just such a series of lamps was created. Your addition of candelabra based lamps may just do the trick! Just received the 7w and 5w to see if they would give me the necessary brightness differences I need in the various locations. Have already used up the 3 new 5w lamps, all to replace original 10w lamps, because they were too bright for the application. Such a lot of light for so little power!

Thanks so much for your detailed review of our Watt-a-Light LED bulbs for use with your solar system! Yes, our newest bulbs are low/no radio interference, so have made some customers very 'happy campers'. Always, great to hear from returning clients who love our products!

Solar lighting in a mountain cabin

These bulbs are excellent, although we found the 3w version too dim (but the 5w are great!)

DC light for tiny off-grid house

After having 2 bulbs not last more than a year from a cheaper competitor, I decided to try Watt-A-Light.I appreciated the customer service with a real person trying to find most economical way to ship to USA, and what would work best in my house. The bulb is working well and hoping it will last a long time.
