[0.6 lb] There are a lot of knock-off bulbs available for 50-75% less, but they are not worth it. They're not as bright and they don't last as long. It may be hard to swallow the cost of an OEM bulb but it's worth it. Your projector will be like new.

[7 x 6.6 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.

[0.6 lb] This was a great value for a replacement lamp for our projector - easy for me to replace myself and now we’ve got a brand new projector :)

[7 x 6.6 x 4.6"] Works as expected. Shipped fast. Easy installation. What more could you ask for? Oh ya, it was less expensive than buying direct from BenQ!

[0.6 lb] A fantastic projector and I’m looking forward to seeing the quality of the higher rated bulb rather then a less expensive one that I ordered last time. Thanks for offering great competitive rates. Once it arrives I’ll tollo l llll

[0.6 lb] Projector lamp works perfectly in my BenQ TH585 and I received my order in 1 day! Lamp was very easy to replace - looking forward to getting many more years’ use out of my projector :)

[0.6 lb] This is an updated review (November 23, 2020).
I first purchased this replacement for my HT1085ST in 2016, for $250. The lamp that came with my Benq projector decided to explode (safely within it's housing) after a mere 1500 hours. At $250 a pop, and believing that one year would be the par for the course, I was beginning to 2nd guess going projector instead of TV.
This bulb has lasted for 4 years and currently has 10,900+ hours. I'm certain it's not as bright as it used to be but it's still has been running great.
Last night was the first time, with an all white screen, I could begin to notice a slight flicker. I wasn't even mad. 11,000 hours, 4 years, yeah, let's' replace you buddy. You did good. Real good.


The price is a decent bit cheaper now too. Looking forward to putting the new lamp in, so long as FedEx can get it here. I live on a main road, but for some reason, Fedex likes delivering my packages to the apartment complex 10 numbers away from me so I always get nervous when I have something arriving through fedex instead of UPS.

[0.6 lb] This purchase worked as described. It was on time. Installed it and it has worked fine for about 10 hours so far! Very happy with this purchase!

[7 x 6.6 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.

[7 x 6.6 x 4.6"] Received the bulb ahead of schedule, it fit, and everything looks better after the last (dimming with age) bulb.
