If you were thinking about 2xT5 this LED will be better than that.

Or this one (more power but needs extra heat sinks)
There are more reviews on same light but 48" model

However some people are reporting SPS color fading with LED's so maybe stay with T5x4 or x6 bulbs or get 2x150W MH with actinics, proven to work.
2x250W is a lot more heat.
