Have you ever tried to replace a lamp shade, only to discover it doesn’t fit? The confusion often comes from understanding the type of lamp shade base you're working with.European lamp shade bases, commonly known as "Euro fitters," are a popular but sometimes confusing part of home lighting.

When you compare incandescent and led bulbs, you see big differences in how they make light and how much energy they use. Incandescent bulbs waste about 90% of their energy as heat, while LEDs use most of their energy for light.

You might wonder how long your incandescent bulb will last. On average, a standard incandescent bulb shines for about 1,000 hours. If you use it for 5 hours each day, you can expect it to last around 6 to 7 months. The actual time can change based on the type of incandescent bulb and how you use it.
