No way could you get them on every bulb. I dont see how it would be worth it because you would effectively block much of the light from the bulbs that didnt have them. They are computer designed, bending them so they are not as wide will definitely hurt their effectiveness. You could wire up an 8 lamp Nova so only the 4 sockets with the SLR's are active but why? You will get, IME, a little bit more light from the 8 bulbs than the 4 with SLR's. Then again, you would save half the electricity and heat and bulb costs for almost as much light. Seems like an expensive way to get a 4 T5 system with SLR reflectors though.
