[0.75 lb] Received the bulb ahead of schedule, it fit, and everything looks better after the last (dimming with age) bulb.

[7 x 6.5 x 4.6"] Bought this for my BenQ HT1085st back in 2016, when the original lamp that came with the projector literally popped after only 1500 hours. 
Having never owned a projector before, I thought that was the norm and that Id be having to pay $250 every year for a new bulb.
Im glad that was not the case. 
This replacement bulb is now at 5,900+ hours, and although it hasnt shown any signs of slowing down, Im about to buy another bulb just to be ready.

You will not regret buying this official BenQ OEM bulb to replace yours.

[7 x 6.5 x 4.6"] Had replaced my projector lamp with a lamp from a different company. It only lasted 7 months and maybe 1000 hours. This one has been in for over a month with no issues. I love the fact that it has a 12 month warranty. That was the big selling point for me. Great shipping and communication about where my product was and what was going on.

[7 x 6.5 x 4.6"] I haven't been able to use it much...but it seems to be working just fine. Hopefully this one lasts longer than the first original bulb.

[0.75 lb] You can never go wrong with ordering the exact OEM replacement. This is the exact Benq OEM Bulb Assembly for use with HT1075 & HT1085st Projectors. It went in properly and easily and worked right. I chose to purchase from B&H over Benq's website despite the same price of the product. B&H had free shipping, and B&H is on the east coast (NYC), as am I, Benqdirect's warehouse is in California. I tend to get things quicker from the east coast. I also felt comfortable buying from B&H.
