lux meters and LED's

[Willyd]

hey friends. Is anyone using a lux meter and can it be used with LED's? I was reading up on them and saw that you can't use them with LED's. NebulaHaze did a video with hers and I really want one lol but not if it only works for any lights except leds.

It’s my understanding that it doesn’t work with leds I got one after I watched the video and like using it just sucks if I ever buy an led I will need another type meter. Someone correct me if I’m wrong hope I am lol.

You need a full spectrum PAR (photosynthetically active radiation) meter for LEDs, which can't be measured in lux. https://www.apogeeinstruments.com/mq-500-full-spectrum-quantum-meter/

I believe Nebula has this $538 model....

You can use a lux meter with the newer white LEDs to get a close approximation of PAR. It’s not exact but it’ll get you close enough to set your lights at the right height. The spectrum of the white LEDs makes a difference so you’ll need to know what your particular fixture uses.

This won’t work with the older LED diodes, particularly the red and blue heavy blurple fixtures.

I have an app on my iphone. It reads the differences in brightness. I use it with leds. Just for fun.

thanks very much guys i'll check all this stuff out maybe not the $500 meter like nebula has lol
