			 HQI will put out approx. 1.6 times the candle power of a mogul halide, and the colour spectrum will not fade as fast as a mogul will.  The HQI should however be mounted no closer to the tank than 9-12 inches.  This makes it difficult if you like canopies.  Look for retrofit units if you have a canopy, they will save you $$.  I have not seen HQI in retro form.
