The 16 LED Superfulex isn't as bright as the 14 LED, neutral white, UltraThin board, that I put in my dome light. I have the LED board in the Left map light, and retained the incandescent bulb in the Right map light, so I can compare them side by side. The 16 LED Superflux board is a much whiter white than than the incandescent it replaced, but it is only a little brighter. I got the 16 LED Superflux in neutral white, to replace the incandescent bulb that came with my car, for the map light. The only possible way to justify the price may be the supposed beam angle range of the 4-chip LEDs, and possibly reliability. I don't know what number 4-chip LEDs are. Make the 16 LED version take a good 4 watts so at 80 lumen/watt it may give around 320 lumens of light! If, it can do that without overheating after a while. the 4-chip LEDs may be able to handle it. I'm not an expert on these but if they changed the resistors or current controller to give more current to the LEDs for a given voltage, it would be even brighter. Needs 13 volts + to become really bright. The Oznium LED panel is nice and bright, but it's not above the competition. It takes about 3.1 watts so it's rather high powered. Most are probably not quite as bright per LED as the Oznium one, but there is 1 that is even brighter per LED and about $7 for a 5050 12-LED panel, I have to squint very hard to look directly at it, and that's with the engine off.
Look on 2 popular online shopping sites and you'll see much less expensive 3-chip (5050 LED) panels. I bought a cool white 16 superflux LED panel a few years ago and have left it on for hours on end a few times with no reliability issues.
