Par 38 LED spotlights

[lovetoreef]

You know, I have been waiting on the LEDs I need for my test lamp. Gonna have to bug some people tomorrow about that. I have tried one setup already and it's very close. Red LEDs are certainly not the way to go.

great i will hold out to order another bulb until these news are ready - thanks for the update ... where do you guys typically announce when these are ready?

Evil,
I have a 44x24x22.5 and would like to put the Par 38 lamps over it. There is a couple of inches of sand and I can set the lights at any level above the tank (I have no ceiling constraints). I am just getting started so all I have is various SPS coral frags and a few fish. I plan on adding some LPS later on. I was thinking about 5 lamps, maybe two 12k and two 20k or maybe three 12K and two 20K. What do you think, anyone can chime in if they want.

i would probably think closer to 7 lamps to completely cover the setup ... you can use several of the 80 degree lens, but, may consider the 60 degree to highlight certain areas..

any progress on the new bulbs?

I am interested in learning more. What should I expect to get for a 96L x 24w x 30H tank?

I just placed an order for a 12"x12"x12" cube and want to use a single 20k bulb, should I go with 40, 60 or 80 degree optics?

Evil66: are there new bulbs commming out? should I wait?

THX in advance

I'm building a 16" cube display, would the 60 deg optics be my best bet as well? I really don't want to light the glass so don't need light spread to the edges. The tank will most likely be a LPS tank with a few zoa's or paly's mixed in.

evilc66....what would i need to light a 25x18x18 for sps? i would like to mix your 20ks and a 2x red 3x royal blue and maybe an all blue, just curious of how many it would take to survive all sps

I am setting up a 40 breeder SPS BB tank with canopy and have 4 T5 set up but want to add one or two of the Par38 bulbs. Here is the canopy.

I would like to stick one in each back corner.

Thoughts on bulbs???

The rock structure will be one maybe two bonsai type columns.

Thanks!!!

I got a 48x18x18 reeftank with an ATI sunpower 6x48" bulbs and thinking of doing something different and replacing the ATI for a bank of par38s maybe 5 or 6 of them.

something like 20k(60)-12k(60)-Blue(80)-12k(60)-20k(60)

what do you guys think?

 

[OldNemo]

Looks tight in there. What are you looking to get from adding the lamps?

Possibly a little more PAR but mainly shimmer. I am also looking at some LED strips.

About what size are the lamps?

Thanks

Evil, what are wide angle supplementals?

 

[JTL]

Ok, I think I get it.

Here's a picture of my 60 cube with 3 PAR 38's 8" above the water. My SPS look better than ever and the shimmer effect is like nothing else except the real ocean.

I really like the spotlight look as opposed to the unnatural effect of making a box full of light.

 

[zygote2k]

almost forgot this one.

 

[JTL]

zygote, are those 12k or 20k. Looks very nice.

 

[zygote2k]

20k's

 

[Haksar]

almost forgot this one.

Nice set up zygote2k.How long have you set up this light and what is the growth on the SPS.Do you have any before and after pics.The PAR 38 has how many LED and what is the wattage.

I have a 01 PAR 38 with 8 1 W LED usinng it in my refugium now to grow cheatos.So far I am having excellant growth.Thinking of adding some frags there.

This set-up has only been running for a month. I experienced zero color loss after switching from 400w mh. SPS are growing as usual.
