I recently got my first professional movie light, it is a used Mole-Richardson 200 watt Solarspot. While the light has seen better days the only problems with it are cosmetic and I got it on Ebay for about 1/3 of the retail price so I was happy.
After I got the light I made an order with B&H which included a spare bulb along with a four leaf barn door for the light, I check the number of the light and got the correct barn door but when my order arrived I realized that the gel holders on my light had been changed, and much to by dismay the barn door could not be attached.
In order to make it work I added on three little aluminum corners to the existing gel holder, now the barn door fits well and you wouldn't even know it was modded unless you looked close.
