The Conversion Bulb for my 600w HPS arrived 5 days ago .. I've been holding off for years
but as these were at silly prices I dived in ($us25.00)
The thing is massive as in fact its a Metal Halide bulb operating in a mogal socket built to hold a 600w HPS bulb
the size at first worrying is understood to be a protective shield around the lamp in case it explodes
after all I've read over the years .. I'm getting about an extra 25%-35% blue light which is a hidden great!
I'll use this for an average of 30 days before installing the 2700k HPS 'red' bulb for 60 days then harvest
just like old school heat output is about the same as the hps bulb
and am currently looking for a 400w hps thats can fit into a 400w M/H light (covert the other way)
you know of any please post
