A lamp comes with a max bulb rating of say 60 W. What determines this max rating and what can be done to increase it?
The max wattage is defined based on the entire lamp design. This means: Wiring, fabric used, heat emission, and other. Therefore, there is no way to safely increase the max wattage of your lamp without putting yourself in danger of setting the thing on fire. What you can do, is using SL lamps. They provide far more light, at lower wattages, and with little heat emission. You can easily use SL bulbs with an equivalent of 120 Watts, doubling your light emission from the lamp.
