[humphreysus]

I read most of the threads and want to know the difference between the $30 GE 20K 175 watt HP sodium bulbs that i can get versus the Ushio bulbs that are $80.light spectrum?reds,bluesyellows?

i beleive that the HP sodium, is just a yellowish bulb.

A 20K bulb should be blueish regardless of the type. I've not heard of this bulb. Do you have any more info?
