Mounting this lamp is very simple and fast.
You just need to screw the lamp, holding it with a clean cloth, into the E40 bulb-holder fitting of your reflector until it will turn no further. Be sure that the lamp is well screwed into the holder.
Now you have to connect your reflector cable to your 250W MH/HPS ballast (it is very important to choose a magnetic or electronic ballast with the same wattage of the grow light, for example - 250w). The Hydroponics Grow Shop recommends you replace your lamp regularly to maintain your garden efficiency.
