Mitras lx7 flickering

[Alvizon]

Hi folks, i'm happy with my lights, and finally find maybe the right spectrum setup for my tank..but i have a little (i hope) problem.

Lamps flickering..is heavy and massive , i cannot do a decent picture of my tank because all cameras i try to use show black disturbing lines like a broken tv monitor..

also try with a phone app software to test flickering of leds and value is very high ..i try also my old t5 and levels of flickering is low or not present..i try to test some other LED fixtures and this issues is very less present.

how can you say me?

fixture now running in HO at 60% total power with some channels at 100% and others very dimmed

thank you

Hi

didn't we already answer this question via email or FB?

Still the same answer:

all LED lights work with PWM for dimming
this PWM has a frequency

the higher the frequency the better you can take photos
the lower the frequency the better is the energy efficiency and you can dim LEDs lower
the LX7 have about 200Hz

maybe settings in the camera can be changed to take better pictures with PWM-dimmed LEDs
