Not so much a mod since all I did was replace seven 1141 incandescent bulbs with 200 lumen "Natural Light" 6500K "Revolution" series LED's by Star Lights. They're certainly bright enough and do make reading a lot easier but the DW said it best when she described them as "institutional" compared to the incandescent bulbs. I did appreciate that they fit the sockets and fixtures perfectly and like the fact that they can be rotated to light up specific areas as well. Most impressive is the fact that the seven lights I replaced use about the same amount of power as ONE 1141 incandescent. Definitely a well thought out product! The fixture on the left is using 1141 incandescent bulbs while the fixture on the right has been converted to LED's. Both fixtures converted to LED Patio light with the stock 1141 incandescent: Patio light converted to LED: While paying $24.99 each for "warm white" LED bulbs just wasn't going to happen, I still wanted a quality bulb that was simple to install and that would be able to handle voltage fluctuations while running on AC or DC. These "Revolution" bulbs are rated to handle between 8 and 30 volts without burning out so that's definitely a load off considering the MSRP and what RV dealers charge for them. Like many who are considering switching to LED lights, the cost is definitely prohibitive but searching eBay, I stumbled across a Canadian vendor selling them in lots of 12 with 2 of the Star Lights fused relays (used to install motion sensing light fixtures) included, free expedited shipping (Canada Post) and "Best Offer" pricing. I paid $123.00 CDN for the lot. Although they don't cast the cozy, warm light we're used to, we'll learn to live with them. I've been wanting to go off the grid for a couple of years now so it'll be nice to have more flexibility in the sites we choose next year and not have to rely on a massive battery bank just to power the creature comforts we've come to enjoy. All in all, if your able to find a good deal on the "warm white" bulbs in and around 250 lumens, I'd recommend that you snag some. If you want more information on the Star Lights bulbs head down to their website and poke around. Each of their product pages has a product video as well.
