lighting for a 10 gallon

[griffithimage]

Hi, I'm setting up a 10 gallon and was looking into lighting options. I really like the "pop" and look of a 20k radium metal halide but not the heat and evaporation problems.
I'm trying to decide between the kessill led pendant a150w and the vertex illuminlux modular led. Will either of these lights give me the look of the radium? I'd like to hear other people's opinions.
Thanks

I just ordered a par 38 led buld for my 5.5 nano. I can let you know on wednesday how i like it. I have heard good things about it.
