I do think their would be a market for at least 100 watt incandescents. Probably not for a large corporation. In the winter I can get 6 weeks continuous use out of a bulb. To me that would be worth paying a couple of bucks per bulb which is still available but I see that supply drying up.
yet 250 Watt heat lamps are still available.
Way more than is needed in many cases, costs more to use, so it wastes far more coal-fired electricity just to make liberals feel good about themselves
