Just received 2 300's we ordered from Guitar Center (trust me, I didn't pay retail). When I was setting them up and focusing the two fixtures, I noticed that on all colors, including white, there was a slight variance in each color between the 2 lights. This is a deal breaker for me and we will have to send them back and get them replaced. Is there anything I can do first to see if it has something to do with the bulb alignment or some other adjustment I can make to fix this problem? Is this something that happens often? It's either a bulb issue or color wheel issue, so should I just order new bulbs and color wheels and see which one is bad? Help please, thanks!!!!
