Blue PL Light

[Limpc]

Hi all,

Most of you might have come across the blue PL light, eg Aqualux 36W Blue.

What actually is the color temp of this light ? For sure, this is not actinic because it is much much cheaper than the true actinic and it does not give the glow on certain coral.

Thanks in advance,

These blue lights don't have a K rating because they are nearly monochromatic blue. Anything above 40000K cannot be accurately measured. Infact, the Radium MH bulbs have already exceeded 40000K!

Hi Tanzy,

Thanks for reply.

Since Blue PL is monochrome, does it have any aid in photosynthesis ? It certainly gives a bluish tint to the water ?

I think it does to a certain extent but I'm not too sure about the quality of the light. I'll prefer true actinics because they are known to be at 420nm.
