RV LED Light Bulb T8 - 18 Inch Fluorescent Tube Replacement, 600 Lumen Warm White (10 Pack) - Perfect for Camper, Motorhome & Trailer Interior Lighting

Initial review, having 2 of these installed (one cool white, one warm white).So far, they're great. Brighter than the 18" T8's they replace. They should definitely be used behind diffuser lenses, though. They're fairly directional, but they can be rotated (end caps can rotate) for better light placement. Minimal reflector will be used because of that, hence the strong need for the diffuser.On the colors: The "warm white" is very close in color to the warm white T8s. The "cool white", however, is not. It's a nice, reasonably white light with no obvious color cast - but it's definitely "cooler" in color temp than the T8s it's next to. Far brighter as well.Wiring is straight forward, at least on my thin-lites, just bypass the 12v ballast (disconnect the wires that power it), wiggle the new cord plugs into the hole for the wiring, shake it down to the closest end (behind the reflector), and clip it to the plug harness on the bulb. No need to remove the reflector.If your fixture uses 2 bulbs, the harness has 2 connectors, so you're ready to go.The tombstones are unpowered on this setup, and are just there for support.Fairly straightforward and cheaper than a 12v ballast replacement, and significantly cheaper than trying to replace the fixtures. 2 down, only 22 more to go as ballasts fail.....
