Ledon Light Bulbs FAQ's

Will LEDON Lightbulbs fit my light fittings?

What is LED?

Light Emitting Diodes are semi conductors or “computer chips” that emit a strong light when a current is applied.

Is the light quality different to CFL energy savers?

Yes, LEDS are similar to the traditional incandescent bulbs in that they emit light in the full visable light spectrum. CFLs do not cover the full spectrum and therefore produce odd colours and tones.

No, they give 100% light immediately.

What is the colour temperature?

This is a measure of the warmth of the light. Ledon bulbs give 2800K light which is a warm white.

What is the CRI (Colour Rendering Index)?

The CRI is a measure of how an object appears compared to when it is lit by a “perfect” light source (an incandescent bulb is rated as 100) Ledon bulbs are rated at more than 90. (70-80 is considered adequate for office and domestic lighting).

What is the life of a Ledon bulb?

At least 25,000 hours (25 years at 2.7 hours per day).

Will the light fade over time?

Ledon 40W £0.85 per year
