Which LED to use?

[jacko]

For a moonlight, can I just use any blue LED from Radio Shack? Or should I look for some specific kind / spec ?

 

[Scuba_Dave]

When I was looking into them I noticed that they were labelled (maybe not at Radio Shack) by the "spread" or degree/angle of light out put.
IE a 30 angle would be a "spotlite" effect, narrow beam.
Then there was a 60 angle that spread the light out more.
They are also sold by the light output/rating.
I'm not sure of the exact rating that closely resembles moonlight

sent you a pm and I also have some LEDs I bought that I am not going to use

jackie i use the ones from http://superlumination.com/fixtures.htm they are very easy to plug to a 12V transformer

Thanks for the wicked cool link Armando. I seem to remember it now from back in the days of RC, but I had forgotten about it, and certainly wasn't going to pay $60 for a moon light. What a rip off! Anyhow, that site is great, and I'm thinking of getting three, 3-LED fixtures so I can vary the intensity of the moonlight output by switching on 0, 1, 2, or 3 of the fixtures. By varying the intensity, I hope to simulate a lunar cycle. What fixtures do you use?

Matt I use the triple dome. they now have the Jumbo with 24 Leds but it might be too bright.

 

[Matt L.]

Yeah, I saw the Jumbo, and also worried it would be too bright. So I'm thinking of using three, triple-dome fixtures. Based on what you know about the triple dome, would three triple domes over a 90gal be too bright? Or would just one triple dome suffice?

Armando, any pics of your tank with those Triple LED Dome & Utility Lights on?

 

[Armando]

Casino moonlight pix are hard to come out as they should, but i don't have it anyway

 

[clamm]

triple dome are great, i have some normal blue leds you can have if you want them, im using 6 of them along with two of the swivel moonlights you can get at championlights.com

 

[Matt L.]

I just ordered the triple LED dome light from this guy (blue). It may be a while before I have pics of it up, but I'll post them as soon as I can,

for my new tank, i'm thinking about using the 24-LED Jumbo

 

[Scuba_Dave]

We need lighting in ourt new bathroom, I wonder if LED would work

 

[willray]

That's a great idea!Like a nite lite that never needs replacing.

 

[Scuba_Dave]

Our bathroom night light is LED, costs less to run 24x7 then the old 7w with light sensor
I'm thinking of buying a bunch of LED's & wiring them up for light in the house
I have SO many powerpacs from old phones & stuff that have been thrown out

Armando, any pics of your tank with those Triple LED Dome & Utility Lights on?

no pics of the triple led dome yet.

but i got a picture of the JUMBO i received today. not your traditional moonlight, I think I can light up fenway park with this

and now... turned on!
