LED light bulb Comparison Page


  » Lighting products » [Overview] [Comparison Table] [LED Bulbs]


The following table explains some of the characteristics of LED bulbs which enable you to compare them with the old incandescent bulbs.

  • The model number is as its name implies - just an identification.
  • Power is the new wattage range, which is a lot lower than the incandescent levels we were used to, and explains why the LED bulbs use far less power.
  • Brightness is the incandescent bulb power levels we were used to for comparison.
  • Connector. Most LEDS are screw-in types. They can be large or small. Bayonet fittings are the same as most of the old incandescent bulbs.
  • Colour, we hope, is self explanatory. If you need bright light for detailed work, e.g. reading, writing, fine work, etc Day Light bulbs may be your best option. Warm White bulbs give a 'cosier' light generally for a room or corridor.
  • Angle. This may help you decide on the bulb of your choice, depending on whether you want it to light a relatively defined area, or be a more general light.
  • EHS suitable? Most people with ES will need bulbs to be earthed. Some people with only slight ES may be able to use these bulbs without earthing as a main room/corridor light. They will definitely need to be earthed if in a table lamp or floor lamp or a light in close proximity to the person concerned.
Model Power Brightness * Connector Colour Angle EHS Suitable?
EMF-4-DL 4 W 35 W Small Edison (E14) Day Light (6500 K) Spotlight (36°) If Earthed
EMF-4-WW 4 W 35 W Small Edison (E14) Warm White (3000 K) Spotlight (36°) If Earthed
EMF-7-DL 7 W 60 W Large Edison (E27) Day Light (6500 K) Spotlight (36°) If Earthed
EMF-7-WW 7 W 60 W Large Edison (E27) Warm White (3000 K) Spotlight (36°) If Earthed
EMF-65-WW 6.5 W 55 W Bayonet (B22D) Warm White (3000 K) Wide angle (180°) If Earthed

* Brightness is displayed as the wattage required for an incandescent bulb that generates an equivalent amount of light
