The brightness level of a 5 watt LED bulb is equivalent to a 40 watt incandescent bulb.
The brightness level of a 25 watt LED bulb is equivalent to that of a 100 watt incandescent bulb.
The brightness level of a 9 watt LED equivalent bulb is similar to that of a traditional 60 watt incandescent bulb.
A 25 watt LED equivalent bulb is about the same brightness as a 100 watt traditional incandescent bulb.
The brightness level of a 9 watt equivalent LED light bulb is typically around 800 lumens.
A 9-watt LED bulb is equivalent in brightness to a 60-watt traditional incandescent bulb.
A 13 watt CFL bulb is roughly equivalent to an 8 watt LED bulb in terms of light output. Look for an LED bulb with around 8-9 watts and a lumens (brightness) output of approximately 800-900 lm to match the brightness of a 13 watt CFL bulb.
Incandescents produce 10 lumens per watt, halogens about 13 lumens per watt, fluorescents and LEDs 40-50 lumens per watt. Lumens measure the brightness, watts measure the speed at which electrical energy is used.
Strictly the power in watts measures how much energy is used, while the brightness is measured in lumens. Bulb packaging should carry that information. But 'equivalents' are a useful way for manufacturers to bamboozle customers, so halogens often carry an 'equivalent wattage' figure, which means the power of an ordinary old incandescent bulb of the same brightness. If you had a 100 watt old-fashioned bulb, that is replaced by a 70 watt halogen. It could also be replace by a 20 watt CFL bulb that is obviously less expensive to run and lasts much longer.
There is no direct conversion between watts of incandescent bulbs and LED bulbs, as they are measured differently. However, on average, one 10-watt LED bulb is equivalent to an 80-watt incandescent bulb in terms of brightness. So, you would need 8 LED bulbs at 10 watts each to match the brightness of an 80-watt incandescent bulb.
The difference between a 60 watt and a 100 watt bulb is the amount of power each consumes and the brightness they produce. A 100 watt bulb consumes more energy and therefore produces more light than a 60 watt bulb. This can impact the brightness and energy efficiency of the lighting.
A 10 watt bulb may be referred to as a 0 watt bulb in situations where it provides such low light output that it appears to be off or not functioning. This can happen if the bulb is very dim or if it is close to the end of its lifespan. It essentially has minimal brightness, hence the nickname "0 watt bulb".
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
