Haven't had time to install my LEDs yet, but I just plugged one into a landscaping light that I installed as a ceiling light for my back porch. The ones I ordered from Amazon are much brighter than I expected for only 24 LEDs. Turns out that they are described as "5050 SMD", meaning that each individual LED on the panel is 5.0mm by 5.0mm. Many Ebay panels I've seen are "3028 SMD", so each LED is 3.0mm by 2.8mm. As I understand it, the 24 LED 5050 SMD panel is (in theory) about 1 1/2 times brighter than a 48 LED 3028 SMD panel...something to consider when buying. The wife is unsure of the cool white color of the ones I've bought, so we may go with warm white LEDs, and unless the 5050 SMD panels can be found much cheaper than those I've just purchased, I'll be getting the rest of them from Ebay and waiting for shipment from overseas.
