How many Watts does an LED bulb use?
Now, LED’s have changed the game as an LED bulb the uses 15-Watts is no way similar to a 15-Watts Incandescent. Nowadays, companies rate bulbs through lumens as these give you a more accurate indication of how much light to expect from an LED.
What is an LED lamp?
LED lamps were the most recent lights to be introduced and since then a new method of rating was required since the wattage no longer determined which bulb had the superior brightness.
Do LED lights use less wattage?
Watts do not measure brightness but the amount of power used. Since LED’s use lesser wattage and produce the same amount of brightness, they save much more energy. Other than helping lower the electric bills; most LED bulbs are also dimmable and don’t contain any Mercury.
What is the CCT of an LED light bulb?
Incandescent bulbs generally generate a yellowish "warm white" colour with a CCT of around 2700K and a CRI of 100 (as incandescents are the reference light source used in the CRI metric). LED lights offer a much broader range of colour temperatures, ranging from warm white to natural (sometime's called 'pure' or 'daylight') white ...
What color light is best for a room with low light?
Different colour temperatures may suit different spaces and tastes. In general, warm white may be a more appealing choice for spaces with lower levels of light while pure and cool white lighting tends to complement spaces with high levels of light or sunlight.
What is the maximum flicker on a 50 Hz LED light?

How many watts does a flame tip LED bulb draw?
Designed to replace incandescent candelabra bulbs, these flame tip LEDs deliver the equivalent light of 25 – 35 watt incandescent while only drawing 3.5 watts of electricity. Because of the heat sink in the base, light doesn’t disperse downwards as much as a typical incandescent candelabra bulb.
What is an LED bulb?
In this style LED bulb, clusters of LEDs are covered by a lens which spreads the light over a wider area, like standard incandescent bulbs. Available in standard Edison bases, these bulbs are used as area lighting for rooms, porches, reading lamps, accent lamps, hallways and low-light applications where lights remain on for extended periods.
How many watts does a globe bulb use?
Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.
How long do LED bulbs last?
Some manufacturers claim the new LED bulbs will last up to 25 years under normal household use, but this is not proven. Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use.
Is LED dimmable?
Several models are dimmable. Also, because they are 90% more efficient than incandescent bulbs and last 10 times longer than CFLs, the frequency of changing LED bulbs is greatly reduced.
Do LED lights build up heat?
Available in pin base or standard (Edison) base, LEDs are ideal for track lighting. LEDs do not contribute to heat buildup in a room because no matter how long they remain on, they do not get hot to the touch. Also, because they are 90% more efficient than incandescent bulbs and last 10 times longer than CFLs, the frequency of changing LED bulbs is greatly reduced.
What is lumens per watt?

Light Distribution
- Unlike incandescents and halogens, which emit light about all directions of the filament, LED light sources are naturally directional. The light distribution for similarly shaped globes can thus turn out markedly different from each other. Many retrofit globes like the Philips LPRIZE-PRO or FEIT's A19 Omni deliberately emulate the spatial light distribution of incandescent globes, however oth…
Colour Quality
- The colour temperature and Colour Rendering Indexof a light source determine the appearance of the light and the objects being illuminated. Incandescent bulbs generally generate a yellowish "warm white" colour with a CCT of around 2700K and a CRI of 100 (as incandescents are the reference light source used in the CRI metric). LED lights offer a much broader range of colour t…
