So this is a ridiculous thing to admit, but I have no idea whether or not my metal halides are 150w or 250w. I got the fixture off my brother-in-law used and the box and instructions that he provided me with say that the bulbs are 150w HQIs (DE). However, I purchased 2 150w DE HQIs and they are both too short and have the wrong connection on the bulb. In looking around online, the bulbs in the fixture look like 250w DE HQIs. I don't see any wattage listed on the bulbs. Does anyone have a 250w DE I can borrow to test my theory?
Here's a picture of the bulb I pulled out:
Here's what the 150w bulb I bought looked like:
Here's what the 250w bulb from the same sight looks like:
