Mushroom's questionable light preference

[davidcalgary29]

I built a 2g jarquarium about five weeks ago. It was meant as a macro-only jar, but I received a mistake shipment that contained a mushroom frag that, despite spending five days in transit and freezing temperatures in northern Alberta, somehow survived, and plopped it in the jar (my other hadn't fully cycled). I have affixed to it a 9W BR30 Feit "grow" light that "emits light at the desired spectrum between 449nm and 630 nm" and gives off an awful pink glow while doing so. I've grown to hate it, but the mushroom seems to enjoy the light and shrivels when I try to replace it with anything else; I tried a blue light, which made the 'shroom floresce beautifully, but then made it contort and look like it was going to wrench itself off of its frag; a PAR38 white light made it close right up. Moving the mushroom is not an option: I tried it in my other jar, and it immediately began to expel mucus in protest. I moved it back to jar #1 under the gross light, and it recovered nicely. Does anyone have a recommendation for another bulb with a similar spectrum (and without the pink tint) that I can try?

Honestly, mushroom corals are one of the hardest corals to kill.

I would use any light you prefer and keep the mushroom shaded while acclaimating to the new light.
Sounds like it got used to the different spectrum due to its long stent in the mail.

My mushrooms at the bottom of my tank stretch for the light but the ones high up on my frag racks are always splitting for reference.
