PS30 Incandescent bulbs are often 200W or 300W, sometimes even higher. In general they look like large A-lamps and are often found in church chandeliers and similar high-ceiling applications. Previously there were limited options for replacing these especially considering dimming is often utilized with these lamps. But now Green Creative has an LED PS30 bulb! Their 34W 5000 lumen LED PS30 lamp comes in E26 which is dimmable and E39 mogul base which is non-dimmable. E39-base solution however does have SelectDrive capability which is a feature on the lamp itself that allows you to choose between three adjustable lumen outputs on the lamp.
