Power LEDs (working at 220 V)?
« on: October 20, 2017, 05:46:20 PM »
Hi,

Has anyone involved with power LEDs (working at 220 V)? They work at a recurrence of 50 Hz, can I (basically) increase the recurrence to avoid from flashing?

I was looking at these: https://www.icrfq.com/part/2778788-CXA2530_0000_000N00S20E8.html

Thanks for your help.  :)

These LEDs have a CRI "Color Rendering Index" value of 80.
This CRI value is not good for photography especially for skin (also food, nature,...).
It is better you use LEDs with a CRI greater then 90 or better greater than 95!
This Video explains it better.

2700kelvin color temperature is also slightly warm.
Photo LEDs are normally at about 5500 to 5600kelvin.

There are LED Strips you can power with 12Volt DC (=flicker free), they are may be a better solution for DIY Lighting.

for 220V there are these Lamps
