  1. ok i live in calgary ab and need a price check for this 300 watt bulb my friend says is worth 60$ and is hps here is basicly what it looks like: its got 6 filament threads attached togather and is white it also has a metalic shield coating around the sides of the bulb and gives off alot of fucking heat i have no idea what an hps looks like or behaves like so i need some opinions
  2. switch it on......if it gives off a yellowish glow, it's a HPS, if it's more blue than say a houselight, it'll be a MH..........unless of course it's a halogen, which i doubt..........ps, remember you'll need a ballast with thew light, it contains the power unit, and starter for the light........i've noticed most sites in America and Canada, sell them with an external ballast, mines is called a high bay, it contains the ballast and bulb in one unit, but the heat can get a bit much as a lot of growers will run the ballasts out of the growroom, to keep temps down.............Peace out...........Sid
