Hi Wash. I am not sure about the Galaxy but the Phantom is awsome. I recently bought one and am very happy. I have played with the dimmable options but just cannot find myself trying to give less light:wtf: I bought this on GAGROWN's recomendation and am very happy.

Magnetic is what I have used in the past which worked well, but, certainly not the same.

The Phantom digital one is not even close to the same as my old ,bulky, hot and loud units used in the past. Digital is just the oppposite... newer technology (I think) smaller, cooler and quiet. Not sure how long they will last??

When shopping I found the Digilux bulb... they are a little cheaper than the Hortilux, and apparently provide a more useful spectrum and even appear to be built stronger. But....I stayed with the Hortilux (tried and true)
