Wow, what a difference a new lamp makes! My Christie LWU421 is practically brand new again, the colors are vibrant and the picture is so much brighter than before. I'm kicking myself for waiting so long to finally order a replacement from Projectorlamps.com; movie nights are back on!

The LWU421 lamp was a breeze to install and the brightness is a huge improvement—plus, Projectorlamps. com made ordering quick and easy. Their customer service is top-notch; I was pleasantly surprised to talk to a real person right away when I called with a question.
