Wow, what a difference a new bulb makes! My Optoma GT770 is practically brand new again, the colors are so much brighter and the picture is sharp, I almost forgot what it looked like when I first got it. I sourced the replacement from Projectorlamps.com, and I'm really impressed with the quality. Finally, movie nights aren't dim and dingy anymore!

The GT770 lamp was easy to install and delivered vibrant, clear images right from the start. I was impressed with the fast delivery and how helpful the staff was when I called with a question. Ordering through Projectorlamps.
