Par 38 LED spotlights - Page 34

SaltSolutions1 · 02/27/2011, 10:17 AM

I have a ten gallon rimless with a 4 bulb T5 fixture on it right now. I just purchased one PAR38 bulb from rapidled.com

I purchased the 20K 7 LED bulb with 80 degree optics

The tank footprint is 20 x 10

Please offer some suggestions on what I should do with the lighting:

I could run just the PAR38 up high. Will it be enough coverage for SPS?

Could I somehow use both the T5 fixture and the PAR38 bulb?

Thank you in advance for all of your suggestions and input.

The single led bulb mounted at a height for good coverage will grow sps diredtly under the bulb and LPS and softies at the edges. You will need two for total tank coverage though. There is no need for the T5s, but you can use them if you'd like.

Anyone seen a floor lamp to help?

Anyone?

How many and at what optics would I need to cover a 96x18x18 SPS tank. What height should they be placed off the water?
I want to get a away with the bare minimum as I am on a tight budget.

Can you hang any sort of fixture over your tank?

12 with 60* optics would give good coverage. The mounted height will need to be tested by you manually. Mine are about 5" above the water on a 22" deep tank. I should have monted them about 7" above the water for a tad better coverage.

Do not use clamp ons. PAR38s are very heavy and at some point it may fall in.

If the shield is removeable this would work:

If you can mount track lighting on the wall it would be okay, but remember that you will need a stud to screw them into dure to the weight.

2 of these mounted upsidedown:

The tank will only be 18" wide (maybe 20") and will only have SPS in the center on islands - I was thinking I could get away with 6-7 spaced evenly over each of the islands? What do you think?

They emailed me they are not removeable.

I do not think so. I have 9 over my 125 that is 72" long and 18" wide. Maybe 10 for a minimum with dark/dim edges.

I posted a DIY a few pages back. It has worked great for me and I like the look. Pretty cheap too.

ian09 · 03/02/2011, 05:24 PM

Hello all! I was reading through this and was interested in setting this up as well. How many bulbs (and at what optic) would I need for a 30 Gallon Long (36.5" X 12.5" X 17")? I was thinking maybe three hung from the top spaced out in a straight line along the length of the middle of the tank. What do you think? Any feed back would be appreciated, thanks! And if this works, how can I go about being a part of the group buy?

Mikey122687 · 03/02/2011, 05:31 PM

Anyone know where i can get a tall, about 4-5' light socket for these bulbs? I tried HD and Lowes but no go

Anemonebuff · 03/02/2011, 05:32 PM

3x7 LED RapidLED PAR38s will work great. The height they are mounted will need to be played with for proper coverage.

Hi, I am soon to be setting up a 100 gallon tank ( 60"x18"x20) and I was wondering your opinions on this bulb set up. 6 bulbs, 3 -12k and 3 -20k.The bulbs will be placed about 12" off the water, with 60 degree optics. Will these bulbs work to maintain some lower light sps, LPS,and maybe a clam? Thanks, Fish77

b16drag · 03/02/2011, 10:55 PM

I'd probably go with more than 6 bulbs for this 100g setup.
