I want my T5-only tank to shimmer like it has halides!

I heard that I can hook up some white-colored LED's to get the shimmer back.

Question is: At 1 watt per bulb, would they be overpowered by my T5's? Would I still get a shimmer? I'm not looking for a moonlight shimmer; rather, a shimmer when my main lights are one.

Assuming they'll get me the shimmer, I was looking at the following LED's from Current USA:

1) Powerbrite strip (has 4x1W LED's) - costs about $60

2) the Lunar Lights (has 2 LED's) - costs about $13

The Powerbrite's literature says it's "for the shimmer" effect. is it just marketing? Do you think I can get the shimmer from the Lunar lights, which are a lot cheaper?

Thanks
