Gone are the days of just grabbing a 60-watt bulb. Now you’re standing in the lighting aisle looking at a box that says “9W = 60W” and wondering—Is this really going to be bright enough to read my book? Let’s clear that up once and for all. As professional electricians in Redland, we get this question all the time: “How do I know which LED bulb to buy?” The answer lies in understanding how LEDs produce light differently than old-school incandescent bulbs.
Why LEDs Use Less Power
Traditional incandescent bulbs create light by heating a metal filament—basically, you’re burning energy to make brightness. LEDs (light-emitting diodes), on the other hand, use semiconductors to emit light in a much more efficient way. This means they use far less electricity (watts) to produce the same amount of brightness (lumens). Not only do LEDs consume less energy, but they also generate less heat, which helps reduce cooling costs in warmer months.
They last significantly longer too—often 10 to 25 times more than incandescent bulbs. This means fewer replacements and less hassle. In the long run, switching to LEDs is not just about saving energy, it’s about saving money and reducing your environmental footprint. So, when you see an LED bulb that says “9W = 60W,” it’s not a gimmick. It really can replace your old 60-watt bulb while using a fraction of the energy.
Lumens vs. Watts: A Better Way to Measure Light
Here’s a quick guide to match up old incandescent wattages with modern LED equivalents, based on brightness:
| Incandescent Wattage | Brightness (Lumens) | LED Wattage Range |
|---|---|---|
| 60W | ≈ 800 lumens | 8–10W |
| 75W | ≈ 1100 lumens | 11–13W |
| 100W | ≈ 1600 lumens | 16–20W |
Instead of focusing on wattage, look for lumens. The higher the lumens, the brighter the bulb.

If you’re replacing multiple bulbs in a ceiling fan or chandelier, be careful not to go too bright. Too many high-lumen bulbs—especially with a daylight color temperature (5000K+)—can make the room feel overlit and harsh. A warm white (2700K–3000K) with 800 lumens per bulb is usually plenty for living spaces.
