Choosing a new high efficiency lamp - what are the options?
What is your current lamp?
What are your replacement options?
How does it work? What are the benefits? Ideal applications Not suitable for
Traditional incandescent lamp Compact fluorescent lamp Like a traditional fluorescent tube, but in a small format
• Up to 80% energy saving• Long life (about 8,000 hours)• Cooler running than traditional
bulbs
• Direct replacement for traditional bulbs
• Can have a ‘slow’ start, so avoid applications requiring instant start
Light emitting diode (LED) Light emitting diode (a special kind of diode that glows when electricity passes through it)
• Up to 90% energy saving• Ultra long life (about
50,000 hours)• Very cool running
• Direct replacement for traditional bulbs and compact fluorescents
• Difficult-to-access locations
• Almost no limitations
Fluorescent tube Higher efficiency tubes and control gear
Smaller diameter tubes and modern control gear require less energy to produce the same output
• Around 30-50% cost saving over regular fluorescent tubes
• T8 and T5 fittings are more energy efficient than T12 and produce better quality light
• Faster switch on/off• Suitable for presence or light
level control
• Direct replacement for existing fluorescents
• Good for general lighting
• Anywhere not currently suitable for fluorescent tube based systems
Light emitting diode (LED) Light emitting diode (a special kind of diode that glows when electricity passes through it)
• Around 50% cost saving over regular fluorescent tubes
• Lasts about six times longer than regular fluorescent tubes
• Can be retrofitted into existing fittings
• Very cool running
• Direct replacement for existing fluorescents
• Good for general lighting
• Almost no limitations
2D fluorescent tube Light emitting diode (LED) Light emitting diode (a special kind of diode that glows when electricity passes through it)
• Around 50% cost saving over regular fluorescent tubes
• Lasts about 6 times longer than regular fluorescent tubes
• Can be retrofitted into existing fittings
• Very cool running
• Direct replacement for existing fluorescents
• Almost no limitations

What is your current lamp?
What are your replacement options?
How does it work? What are the benefits? Ideal applications Not suitable for
Halogen GU10 (230V) spotlights, MR16 (12V) halogen spotlights
and ‘R’ series spotlights
Compact fluorescent lamp Like a traditional fluorescent tube, but in a small format
• Up to 75% energy saving• Long life (about 8,000 hours)• Cooler running than traditional
bulbs
• Direct replacement for GU10 halogen bulbs
• Can have a ‘slow’ start, so avoid applications requiring instant start
• No direct MR16 replacement available
Light emitting diode (LED) Light emitting diode (a special kind of diode that glows when electricity passes through it)
• Up to 85% energy saving• Ultra long life (about
50,000 hours)• Very cool running
• Direct replacement for existing bulbs, but 12V systems will require a special LED driver to replace existing transformer
• Situations where access to replace existing transformer is not possible for 12V systems
Mercury vapour HID lamps Sodium vapour or metal halide lamps
High voltage excites gas to produce light
• While all HID lamps are more efficient than incandescent lamps, metal halide and sodium HID lamps are more efficient than mercury vapour lamps
• High level lighting• Exterior lighting
• Anywhere requiring instant light as these lamps can take several minutes to ‘strike’
• Colour rendering can be an issue, especially with low pressure sodium light
Sodium vapour or metal halide lamps
Light emitting diode (LED) Light emitting diode (a special kind of diode that glows when electricity passes through it)
• Up to 60% energy saving• Ultra long life (about
50,000 hours)• Can be switched off or dimmed
by automatic controls• Improved light quality
• Difficult-to-access locations often at height
• Storage areas used irregularly where presence detection can be used
• No limitations

Exterior security lighting Compact fluorescent Designed to incorporate a compact fluorescent lamp
• Up to 75% energy saving• Long life (about 8,000 hours)• Cooler running than traditional
bulbs
• Direct replacement for incandescent bulb based systems
• Anywhere where the ‘slow’ start of compact fluorescents can cause a security issue
