I wired up a pair of these 20” bar lights in my neighbor’s trailer to replace the incandescent lights that came with the unit. He’s quite happy with the result as it is brighter and more efficient than the wussy lights the manufacturer supplied. I used the natural white version since I had a bunch of them on hand but you can get warm white. You can’t beat the price. Less than $5 for a pair of them with clear or milky cover. I looked and you can find CRI90+ lights but the price goes way up…
