The saki is almost identical to the pheonix... so I dont think you will get much there. The g-man is similar to the Ushio 14,000K... its like a 10,000k with some purple in the output (alot actually, but you just dont see it because of all the red/yellow/etc). I love this bulb though because all you have to do is add a blue+ T5 bulb to it, and its icey day-blue looking. Corals love it too.... red ones and blue ones...
Here is a pic of the ushio 14,000Ks with the blue+ T5s... the G-man is pretty much just a higher intensity ushio 14,000K looks wise...
