Question regarding MH bulb choice

[Sangogo]

I have a question regarding MH bulbs. Currently, I use a 150W clip MH, which shines directly over my haddoni anemone. I know that a haddoni anemone doesn't need as much light as a gigantea, but I can't seem to find a recommended range of light for a haddoni.

The current bulb, which also includes a blue spectrum, is on the whiter end of the spectrum. According to specs, it emits 2800 lx at one meter depth, which is probably more or less the distance between the anemone and the lamp and emits a total of 9000 lm.

I would like to switch to a bluer bulb, which would be much more attractive. The next bulb in my range of blue emits 1300 lx at one meter and emits a total of 2500 lm. Is this enough light?

(If you think I should post this in the lighting forum, please let me know.)

In my experience, haddoni, like many other anemones will reach toward light if it is not receiving enough PAR.

Healthy and happy haddoni will be on the substrate and will achieve maximum expansion within an hour or so of lights on.

If the anemone contracts within the first few hours of lighting, light may be too intense. Acclimate it to the more intense lighting slowly.

If the anemone continues stretching toward the light, lifting off the substrate, light is less then satisfactory. Reduce distance of the fixture, change bulbs, increase wattage, increase PAR, etc.

Best of luck.
