LED lighting

[justahobby]

All these nano and pico threads has me contemplating setting up a 10 gallon I have laying around. I was looking at this light and thought I would get opinions from more light savvy folks. It appears to be 65k, Par 38 w/ 5 X 8 watt LEDs. Does the par sound like enough for a mixed reef? I would also supplement w/ 420/ 460 nm actinics.

Pretty sure 6500 Kelvin is going to be really yellow. Corals will probably like it...but it's going to be ugly like a fuge light even with supplemental lighting.

You are probably right, I haven't seen 65K in person to know just how ugly it would be. I was thinking some deep 420 nm could wash it out while giving me killer growth. I looked at sanjay's lighting guide and saw some low end 150w MH had a par in the 30's so I think the par would be ok. It's really hard to find a 10K (much less any kelvin ratings) when shopping hardware stores.

6500K is WAY yellow. I have some 4 foot T5's that are 6500K. Next time you are at the house I'll put one in my fixture and let you see it. Makes the tank look kind of ugly.

[Mr Cob]

my last fuge light was 6500k , it was very yellow. Maybe you could pull it off.

[Mr Cob]

Hey...maybe you could make green if it's yellow enough and you supplement. That would be super ugly and cool at the same time.

[txav8r]

LOL I like it!

[justahobby]

65K is ugly as sin eh? Alright, I will keep shopping around and see what I can find.

"Dude, that's a sick tank!" :sick:

We may have exaggerated a little bit. But yeah...it's pretty ugly. LOL!

[justahobby]

I guess I could use it to grow the coral out and then switch to a nicer light when it's full. I have my 58g DT so it's not like I wouldn't have a prettier tank to look at. It could be my "butterface" tank.

[Mr Cob]

nah dude...use it to grow the coral and if anyone comes over just turn it off and turn the actinics on. LOL! They'll never know.

[justahobby]

Ah, good plan!

Justin You can look at my LED Lights tom. they are really nice and not yellow and best all they are way under 1000.00 .

[justahobby]

I would love to see them. I've been wanting to see someone's LED system.

Here is the par38 LED bulb I have: http://maast.org/forums/showpost.php?p=703720&postcount=155

It's from nanotuners and is 12k, but comes in other spectrum choices...

Awesome color. Do you have a pic of it on your tank?
