Home / What wattage light bulb do you need

What wattage light bulb do you need for replacing your existing dead light bulb?

Do you have a dead light bulb? Are you finding it complicated on choosing the right bulb for your replacement?

With new technology such as LED home use light bulbs and Compact Fluorescent bulbs, Which one shall you choose?

Back in the day when LED was used for small devices, A 100W bulb was brighter than a 40W bulb but this isn’t always the case anymore. Energy saving technology like compact fluorescent and LED mean you can get a light bulb as bright as your old 40W incandescent that uses, for example, just 5 Watts of electricity.

To make sure we get the correct replacement bulb in terms of the brightness (because you don't want to lose any brightness, right?) we need to think in terms of light output.

Light Emitting Diode (LED) 2W - 4W 5W - 7W 8W - 10W 9W - 13W 13W - 18W
Compact Fluorescent 5w 7w 11w 15w 20w
Halogen 18w 28w 42w 53w 70w
Incandescent 25w 40w 60w 75w 100w
Lumens (lm)
lumen brightness

230 - 375 lm

400 - 500 lm

700 - 900 lm

900 - 1125 lm

1300 - 1500 lm

If you want to replace your 70W halogen light bulb with a modern LED, the LED will probably use between 13 to 18 Watts of energy.

What is Lumens? / "lm"?

If you imagine one lumen is approximately equal to the amount of light put out by one birthday candle that's one foot away from you, a standard 60-watt bulb puts out around 750-850 lumens of light.

luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela.
