I bought this secondhand. It looks unused but I have no idea. I also have no way to test it. It looks like there are cracks towards the back of the bulb. I don't know if this is a defect or typical. I'm selling it "as is" Please email me with any questions before purchasing. I don't know anything about this so I'm selling it for half the price of the cheapest listing on eBay. Take your chances on this listing. I'll pack the heck out of it for shipping but I can't guarantee the post office won't treat it like a hockey puck.
