Light Bulbs

Brightness (Lumens)

• Lumens measure the total amount of visible light emitted by a bulb

• More lumens = brighter light; fewer lumens = dimmer light

• A standard 800-lumen bulb replaces a traditional 60W incandescent bulb

• For reference: 450 lm = 40W, 800 lm = 60W, 1100 lm = 75W, 1600 lm = 100W equivalent

Colour Temperature (Kelvin)

• 2200K – 2700K: Warm White – cozy, amber glow for living rooms and bedrooms

• 3000K – 3500K: Soft White – warm neutral for dining areas and kitchens

• 4000K – 4500K: Natural / Cool White – balanced, crisp light for offices and task lighting

• 5000K – 6500K: Daylight – bright, blue-white for garages, security, and detailed work

Energy Efficiency (A-G Rating)

• LED bulbs are rated A and use up to 90% less energy than incandescent bulbs

• Energy labels run from A (most efficient) to G (least efficient)

• 90% of the energy used by incandescent bulbs produces heat, not light

Lifespan

• LED: 15,000 – 50,000 hours (10-20 years of normal use)

• CFL: 8,000 – 10,000 hours

• Halogen: 2,000 – 4,000 hours

• Incandescent: 750 – 2,000 hours

Dimmable

• Dimmable bulbs work with compatible dimmer switches

• Not all LEDs are dimmable – check packaging before purchasing

• Dimmable bulbs allow you to adjust brightness from 10% to 100%

CRI (Colour Rendering Index)

• Measures how accurately colours appear under the light

• CRI 80+ is standard for general use

• CRI 90+ is premium for art galleries, retail, and spaces where colour accuracy matters
