LEDs Magenta

I was using a Bescor 95D LED fixture for a lighting workshop at a local college. They own the light and I hadn't used that brand before. It looked very magenta. Is that a known issue with this particular brand?

I know nothing about this particular light.

I'll just comment that if it "looks" magenta - that might be because the LEDs in use had an obvious green spike.

A magenta filter is used to correct for excessive green.

Realize that you're applying a filter to light that's already skewed towards part of the spectrum because it lacks the full necessary components of white light - so you're filtering an already "filtered" source.

A good camera can usually figure things out and make a pleasing picture - but don't be surprised if something that's orange in the scene skews toward brown - or something that's supposed to be aqua skews blue.

That's sometimes the issue with inexpensive light sources. Things overall appear to be OK - but not so OK in the subtle details.

For an office scene, it's no big deal. For a shot of a truck in a garage that has the company logo - and the logo colors matter to the client - it can be a significant issue.

Color accuracy can be the collateral damage of inaccurate light.

FWIW.

Thanks for the reply. I've shot a lot of film over the years and have used plus and minus green extensively. I was more curious as to whether this brand is known to exhibit this flaw more than others. It feels pretty cheap with its light plastic case. But since the college's budget is tight these will work nicely for the students and gave me the perfect example to demonstrate what a green spike is especially when shooting under fluorescents.
