Any electrical/led light experts out there?

Looks like they would run at 1w Max power, so you would need a whack of them to make them work. They do look cool, but how many lumens do they put out. How much par?

You can apparently see these things from 15kms away, so I assume extremely high. they are the lights that light up Rogers arena and the new Bay bridge in San Francisco

There are 50 modules per strand and I think there are 8 leds per module

17,004 cd / m2 lumens per module. Can not find par and I have no idea what lumens I should be at for a reef tank etc , hence why I need advice.

One strand of these lights are around 1200.00 bucks, willing to part with enough for someone else to make a light themselves in exchange for helping.

For those lights you will need to use the controller made for them..
Each light is individually addressed, so if you provide power they will not light up until they receive a control signal.

you need to be able to control the UV output on these, not sure if its worth the time invested, im sure you could just buy a setup for cheaper

in the spec it tells: Each node produces full-color, daylight-visible light output of up to 11 candela. -

1 candela = 12.57 lumen

http://en.wikipedia.org/wiki/Lumen_%28unit%29

A full sphere has a solid angle of 4·π steradians,[1] so a light source that uniformly radiates one candela in all directions has a total luminous flux of 1 cd·4π sr = 4π cd·sr ≈ 12.57 lumens.[2]

so if you have 50 nodes, you have 628 lumen,
I might be missing something, but this is not much

again, unless I miss something

Thanks guys
I know nothing when it comes to electrical, but if you are right. then it does not seem like much. Then again, what about Par and PUR...

You can get controllers that fit in a outlet box all the way to a 24 volt controller made by phillips. There are other brands that can control them as well. The controller is not really my issue. My issue is tryiong to find out if it give the right amount of "intensity" and "Pur". Do they have the right spectrum etc...

An Electrician I am not. You figure for a grand a string they would be good for a tank....

Spec sheet shows 30 lumens per node
