I have a similar light for my daughter's freshwater aquarium, unfortunately as you can not adjust or know par strength of these (think just made in china at cost approx £10) , this is possibly the reason why your anemone is hiding.. the lighting could be too strong and as you say it comes out with standard cieling light then hides once you turn on aquarium light, I would assume the aquarium light is the issue.
You need to invest in a light that you can adjust, also with multi colour spectrum.
what size aquriam do you have please?
Also I would not assume anemone has died as it has hidden, my anemone hide in a cave for approximately 4 months (luckily I could see it) before slowly coming out
Hope this helps
