Why are these LED Bars so cheap?

[strike2867]

I'm looking at http://www.virtualvillage.com/2-x-1....html?utm_source=googlebase&utm_medium=shcomp. I have a regular 90 with a 500 watt MH fixture. The MH fixture doesn't have any T5 supplementation, so I was thinking of getting a pair of the bar sets in the picture(for a total of 4 bars) and just tying them perpendicularly onto the fixture. With a photoperiod of 10-12 hours for the bars and 6 hours for the MH. Can anyone tell me why this is a stupid idea, or why I wouldn't get the colors/water penetration I want? Just seems too easy and cheap...

those don't look like 'aquarium' bar lights, per se. and at $18.99, that's less than $2/LED.
Equivalent blue light bars from good manufacturers cost a bit more.

I'd be wary, IMHO

They will make a nice night time viewing lights.

If not these can someone recommend a similar product that would fit my idea?

My fixture has night lights, which I keep off actually. I was more thinking of these as just actinics.

Given the price, it can't hurt to give it a shot and see how they look.

Do lights outside the 6 hours of MH light need to have much par? I could see if I can replace a few of those with whites.
