Finally Found A 48-SMD 12-Volt Panel
Yeah Yeah Yeah My aged eyesight ain't so hot. I need bright light. Until I tried this plate I might as well have been using a night light to see by. Since I am a law ignoring tax evading shopper th...

I checked and ye gods the lumens now read 240 on their website. Was 270.
Unless there is a substantial difference in watts/lumen between the 3528 and 5630 making the 5630 operate cooler I would hate to see any plate run warmer than what this one does. It gets ****ed warm, and it's a good size plate. Operating voltage test was 12.23
Regardless. I let my eyes and small font print tell me how much light there is. Chinese lumen measurements must not be an exact science and after spending a FORTUNE on hyper overpriced origin-USA CREE and Bridgelux lamps that were a joke for brightness, I think I'm going to stick with this one from BuyInCoins.
The heat is -the- issue and the -hype- is the trap. Only so many watts of chips can be mounted on a given area of substrate and after the limit is exceeded a pretty little mushroom cloud forms. And I am not going to pay a vendor ten dollars a chip premium because he distributes made in China LED plates from a USA post office box.
You'll make less heat with a bigger LED chip and underdriving it /dimming it by using some sort of PWM dimmer feeding it less milliamps. I don't think you'll find problems with the 5630's that are being used in boxlights and signs having cooling problems, usually they are pre built on a good aluminum heat sink that the substrate is mounted on.
