Hi, Can anyone help me with this problem. I'm looking for a very low wattage photo bulb for my MXT. Using the Beseler condenser light source. I'd like one about oh, say 15-25 watts. I'm using the 75watt GE lamp now. I'd like less light. I have a device to "turn down" the 75 watt bulb but the color changes quite a bit at the lower wattages. Any experience with non photo light bulbs and how they might do? Thanks.
