Led Light Bulbs 40 Watt Equivalent

By | August 31, 2022

  1. Compare wattage
  2. Think in terms of lumens and forget about watts!
  3. Colour temperature
  4. LED lamp or energy-saving light bulb?

Did you know that the lighting in the average habitation uses effectually 16% of the total power consumption? This means the lighting in your home holds considerable toll-cutting potential! Replacing your one-time lamps with a modern alternative is a good get-go.

In order to assist you choosing the right bulb, y’all will discover below a serial of handy comparison charts almost:

  • the ability (expressed in watts)
  • the lite intensity (expressed in lumens)
  • the colour temperature (expressed in kelvin)

When replacing an incandescent seedling or a element of group vii lamp, you will now have to choose between a LED or a compact fluorescent low-cal. Just what exactly is the difference?

Compare wattage

The comparison chart below shows you exactly which energy-saving light bulb or LED lamp you lot can replace your quondam incandescent light bulb or halogen lamp with to become the aforementioned corporeality of lite (i.e. the power expressed watts).

100 watts 60 watts 25 watts 12 watts


(1) off the market since i September 2012
(2) gradually phased out from 1 September 2022

Retrieve in terms of lumens and forget about watts!

The light output of LED lamps continues to increase exponentially yr by year.  Which is why the
comparing chart above merely serves as a guideline
. Where a 7-watt LED lamp is currently required to deliver a certain low-cal intensity for instance, in a yr from now, this may well have dropped to just v watts, and is likely to accept dropped fifty-fifty further to simply 2 watts in four years’ time.

Handy tip: the rule of thumb is to divide the number of watts of an incandescent lite bulb by 10, which will give y’all the judge number of watts of a led lamp.

Looking to supervene upon an old incandescent light bulb and don’t exactly know the equivalent LED lamp? The best mode forward is to get by the number of lumens, which is now clearly specified on the packaging.

Traditional seedling Luminosity
100 watts one.300-1.400 lumens
75 watts 920-1060 lumens
60 watts 700-810 lumens
40 watts 410-470 lumens
25 watts 220-250 lumens
15 watts* <150 lumens


(*) lamps for refrigerators or ovens with very low lite intensity

Colour temperature

Alongside the lite intensity (number of lumens), the color temperature is another deciding factor when choosing the right LED lamp.

The appropriate colour temperature enables you to cull the
ambiance

you would like
for each room. Colour temperature is expressed in kelvin. The higher the colour temperature, the
higher
the Kelvin rating and the
more blueish
the color. Calorie-free sources with a (comparatively)
low temperature
tend to be
more than reddish.

To give y’all some idea, below is a summary table showing the near common light types and their corresponding colour temperature:

Cool white 5,500 to 6,000 kelvin
Neutral white 4,000 to iv,500 kelvin
Warm white 2,500 to 3,000 kelvin
Yellowish white +/- two,200 kelvin

Observe out more than about colour temperature

LED lamp or energy-saving low-cal seedling?

Incandescent light bulbs are no longer an option, with element of group vii lamps besides now on their style out. Which means the duel is now between compact fluorescent lights and LEDs. A quick reminder …

Free energy-saving light bulbs

The free energy-saving light bulb, as well known as the compact fluorescent lamp, is actually a
folded fluorescent strip tube lamp
that fits within a regular bulb plumbing fixtures.


Benefits

  • use 65 to eighty% less power
    than a traditional incandescent calorie-free bulb
  • last a lot longer (ca.10,000 hours
    instead of 1,000 hours for an incandescent lite bulb)


Drawbacks

  • contain a small-scale amount of mercury: if an energy-saving calorie-free bulb drops to the flooring and breaks, please be very conscientious how you make clean information technology up because of the
    hazardous mercury vapours.
  • get
    very hot
    compared with LEDs; they dissipate energy on oestrus, although to a lesser degree than traditional incandescent low-cal bulbs or halogen lamps.
  • most CFLs take
    a while to work up to total low-cal intensity, which makes them unsuited for use in places where the light is switched on and off for brusk lengths of fourth dimension (like the toilet).

LED lamps

LED lamps are fabricated upward of clusters of
light-emitting diodes
(LEDs). Every bit they are so small, LED lamps come in all shapes and designs.


Benefits

  • use
    up to 80% less energy
    than incandescent light bulbs
  • accept a service life of anywhere from
    20,000 to 40,000 hours
  • emit
    light right away
    and
    barely oestrus up
  • are
    shock and vibration-proof
  • available in a wide number of
    colours


Drawbacks

  • comparatively expensive
    in terms of buy price, only depending on how often they are used, the added outlay is recovered over time
  • are dimmable, subject to a number of conditions
