PAR 20/30/38 LED Lamps
Long story short, I had to break down my 90 gallon tank last month because we had several pipes break in our house (only in the dining room / fish room of course), and we are moving in a few months, so I'm going to convert it to an emersed setup for now.
Anyways, I was at Lowes earlier getting supplies for the emersed build and saw their Utilitech PAR 20/30/38 LED lamps. I have a few of those Dayco clip-on dome fixtures with some 23W CFL bulbs (6500K) and was wondering if I could swap out those bulbs for some of the Utilitech 5000K PAR 20/30/38 lamps, provided that they fit in the first place? If I could,
1) would you recommend them over the current CFL bulbs, and
2) could I place the dome lights directly on top of a glass lid? I think it would be okay for the CFLs, but I'm not sure about the LEDs: I think I need more air flow to keep them cool than would be possible with them sitting directly on a glass lid.
There won't be much airspace for the light to travel before hitting the plants in the tank. I am thinking about putting some egg crate shelf in the tank and keeping the tank ~1/2 full (so 10-12" from the soil to the light).
Thanks in advance!
