hi guys,
im using one too.....the problem with this MH is that the ignitor vibrates and make a rattle sound sometimes.
Also, this MH does not come with a capacitor.....to my supprise when i dismantle the MH. the manufacture want to save on cost maybe!
Also, the 4 PL lights comes with 4 magnetic ballast.......that is the cause of the weight. Now, im replacing it with 2 x dual eballast.
Now, after the rattling sound, i have decided to modify it to house DE 2x250watt with the gear being external.....
Hope that the glass for this fixture is UV coated....
