BTW, the price on these modules has now dropped to $4 each. You can probably get them cheaper if you buy in bulk.

We really like the light quality from these. (2700-3500K) I tested some "pure white" (5500-6500K) modules and hated them. The light was way too blue.
People who drop by our trailer often think we are connected to AC power because our lighting is so good. Even when we are connected to AC, I don't turn on the inverter charger, simply because there is no need. The solar panels easily top up whatever charge is used for lighting.
I have no affiliation with any eBay sellers.
