Electricity-competition.co.uk -website's lamp selection recommendations, you can quickly find the most suitable lamp for your application to replace an incandescent bulb.

By replacing your incandescent bulb with another, you save electricity and money. To maximise your savings, we also recommend that you electricity contract tendering.

What kind of luminaire or space do you need a lamp for?

General lighting

If the lamp is not dimmable
LED lamp

Pros:

+ Lights up immediately
+ Highly energy efficient and long-lasting
Cons:

- More expensive purchase price

This is how you can identify a good quality LED lamp by its labelling:

Energy class: A+
Colour temperature: 2700-3200 K
Lamp life: 25 000 h
Number of ignitions: ≥25 000
Check the packaging to make sure that the lamp produces enough light!

Check in which direction the lamp is emitting light. Not all "omnidirectional" LED lamps necessarily produce light in all directions.

Energy saving light bulb

Pros:

+ Energy efficient
+ Longevity
+ Good light output

Cons:

- Slow ignition, also fast ignition and brightening models available

Check the packaging to ensure that the lamp is suitable for outdoor use. In this case it will also work well in cold weather.

This is how you can identify a quality energy-saving light bulb by its labelling:

Energy class: A
Colour temperature: 2500-3200 K
Lamp life: 12 000 h
Number of ignitions: >12 000

If the luminaire is dimmable

Halogen bulb with filament

Pros:

+ Lights up immediately
+ Works well in dimmable luminaires

Cons:

- High energy consumption
- Short lifetime

Dimmable LED lamp

Pros:

+ Lights up immediately
+ Highly energy efficient and long-lasting

Cons:

- More expensive purchase price

This is how you can identify a good quality LED lamp by its labelling:

Energy class: A+
Colour temperature: 2700-3200 K
Lamp life: 25 000 h
Number of ignitions: ≥25 000
Check the packaging to make sure that the lamp produces enough light!

Check the packaging to see if the lamp is dimmable. Also check in which direction the lamp emits light. Not all "omnidirectional" LED bulbs necessarily emit light in all directions.

Choose the amount of light you need based on the snow value.

Candle-lit halogen lamp
Pros:

+ Lights up immediately
+ A radiant white light that makes the crystals sparkle beautifully

Cons:

- High energy consumption
- Short lifetime

Spotlighting

If the luminaire is dimmable
LED spotlight
Pros:

+ Highly energy efficient and long-lasting
+ Long life makes it a good choice if the luminaire is in a difficult to access location

Cons:

- Dimming can be problematic

Make sure that the lamp is compatible with the dimmer and transformer!

How to choose a lamp

Choose the right type of lamp

Lamp selection - table

Check the bulb stock

Ensure sufficient light levels

The lumen value (lm) on the packaging indicates the amount of light. From the table
you can see the energy-saving and LED light bulb equivalent to a given wattage incandescent bulb.

Switching to leather pays off

Led lamps offer many advantages over incandescent lamps:

  • Low energy consumption
  • Long life, up to 25 years
  • Low total cost of ownership
  • Lots of choice in light colours
  • Light up instantly
  • Do not contain mercury
  • Don't get hot like incandescent bulbs

Useful information on labelling

Explanations of labelling

Switching to leather pays off

Explanations of labelling

  • Lumen (lm): Lampun photocurrent. Lumens indicate the amount of light a lamp produces.
  • Watti (W): Lamp wattage.
  • Lamp wattage and equivalence to an old incandescent lamp: The marking helps to compare the amount of light from the lamp with the old ones
    for light bulbs.

  • Colour temperature, Kelvin: Warm white (2700-3200K), neutral white (3200-4000K) or cold white (4000-6500K).
  • Colour rendering: Tells you how well the lamp reproduces the colours of objects.
  • Perfect colour rendering is Ra = 100, Ra=80 minimum, Ra>90 very good.
  • Average lifetime in hours/years: The burn time indicated on the packaging is an average, not a promise of longevity.
  • Mercury contentMercury is only present in small amounts in energy-saving light bulbs.
  • Warm-up time 60 to % light output: Energy saving light bulbs can take a few seconds to light up and 60 % light output reaching up to a minute. LED and halogen lamps light up and brighten instantly.
  • Energy class A-G:  The label indicates the energy efficiency of the lamp. The best energy efficiency on the market lThe batteries are of class A++. 
  • Number of ignitions: Tells you how many times the lamp can be lit.
  • Dimmability: If the luminaire has a dimmer switch, choose a lamp suitable for dimming.
