EEVblog #1303 - New Lab LED Panels

Dave finally found some high CRI, 5000K, low glare LED ceiling panels. Or has he? Will they measure up?

Fixed link:


$80 for that setup sounds very reasonable. Only downside like you say, slightly lower efficiency of 96lm/w vs 130-140lm/w for competing panels.

Plastic seems to be called "prismatic diffuser": https://diffuserspecialist.com/wp-content/uploads/2018/08/p12.pdf
Which is ~90% efficient. I'm going to assume thats taken into account in the lm/w figure of the panel. So the LEDs themselves are closer to 110lm/w.

This looks very nice. Are there cheaper flicker free alternatives for general workshop lighting?

LED strips work great. Mix warm white and cold white to allow fine tuning the color temperature. RGB gives you even more adjustment, if you can get the colors to mix well enough...
Cryptocurrency has taught me to love math and at the same time be baffled by it.
