I was just recently turned onto the PAR 38's (thx zygote)and have a few questions

My 30g cube dimensions are L 20.5 x W 21 x H 18.5

 

I'll probably go with the 20k LED's, but how many should i get two? three?

 

If I do get two will they both be strong enough for my anemone and clams?

 

These two LED's WILL replace my lighting system (aquaticlife t5HO 4x24w) so i would like for them to light my whole cube, but my rockwork is just one large piece of LR in the middle so i want the LED focused in on the rock but i dont want the edges of my tank untouched with light (I dont want the "lightbox effect"). With that being said which angle optics would be best?

 

thanks

I'd go with 3) 40 degree bulbs. You can raise or lower the bulbs to determine how much spread you actually get.

The anemones don't require high light and clams may be better off lower with these bulbs. If you want more spread, but less par, go with 60 degree optics.

Will the three bulbs be enough for my anemone and clam?

Thanks

It will be plenty of light.
