Term | What It Measures | What It Tells You |
Wattage (W) | Power consumption | How much electricity the light uses |
Lumens (lm) | Light output | How bright the light actually is |
A good way to judge light quality and energy efficiency is to check lumens per watt (lm/W).
*Definition: Wattage measures how much electricity a bulb uses.
*Example: A 60W incandescent bulb uses 60 watts of power.
*Key Point: Higher wattage doesn’t always mean brighter light — especially with LEDs, which are far more efficient.
*Definition: Lumens measure the actual light output or brightness.
*Example: A 10W LED can produce 800 lumens, the same brightness as a 60W incandescent bulb.
*Key Point: The higher the lumens, the brighter the light.
Light Type | Power (Watts) | Brightness (Lumens) | Efficiency |
Incandescent | 60W | 800 lm | ❌ Low |
CFL | 15W | 800 lm | ✅ Better |
LED | 10W | 800 lm | Excellent |
*For brightness: Lumens matter most.
*For energy use: Wattage matters for efficiency and electricity costs.
*Best balance: Choose higher lumens with lower wattage (i.e., high efficiency).
When shopping for LED flood lights:
Look for lumens first.
Check wattage second (for energy savings).
Example:
“14000 lumens, 100W LED” → bright and energy-efficient.
