All LED's have a useful life of 100,000 hours |
The amount of useable or meaningful light–about 70% of original light output–from some LED's has been shown to be 6,000 hours or less, depending on the colour and manufacturer of the LED. |
Modern High quality LED's (eg; Luxeon) retain 70% of initial light output after 50,000 hours. Current generation high quality LED's such as the Luxeon have been designed to outlast all conventional LED's–especially in White. |

LED's don't create heat |
LED's DO create heat but the heat generated is retained in the LED package and needs to be conducted away by the package or leads. Without proper design, the LED will fail very early in life. |
Modern high quality LED's have been designed for high power AND high heat. Some packages are able to handle the heat generated, and dissipate the heat to external heat sinks. Traditional LED's–by
design–can't handle the heat |

LED's do not produce enough light for general lighting applications |
High power LEDS do emit enough light for many specialty and general lighting applications |
Modern high quality, high-powered, high-flux LED's emit enough light for illumination applications. LED's already power theatrical spotlights, high power flashlights, and even automotive headlamps! |

White light from LED's is not good enough to replace incandescent light. |
Most white LED's offer light in the 5500K range. Very few offer a colour temperature that replicates incandescent light. |
Modern High quality Warm White LED's give high brightness light in a 3200K output. This spectral output closely matches the blackbody curve. Some modern high quality LED's can replace incandescent bulbs |
| 5 |
LED's do not have high enough CRI (Colour Rendering Index) for lighting applications |
Typical white LED's offer CRI in the 60-70 range, in both 3200K and 5500K |
Modern High Quality Warm White LED's offer incandescent like CRI of 90+, delivering excellent colour rendering |

High-power LED's are
Expensive' |
High-power LED's can be the most cost-effective LED available when measured in lumens |
New generation LED's offer better lumens / $ than traditional LED's |
| 7 |
LED's are more energy efficient than any other
light source |
White LED's are about twice as efficient as incandescent bulbs. Because of the directional nature of the light from an LED, you have more control of the light enabling higher overall luminare efficiency |
This generation's High Quality LED's have been designed to offer extremely efficient lighting solutions. Different light output radiation patterns allow designers to utilize all the light from the LED. |
| 8 |
The colour inconsistency of white LED's is too great to be considered for general
lighting applications |
Because of the nature of white LED manufacturing, a range of colours is produced. Care must be taken during luminaire design and production to manage this colour distribution, to produce a quality lighting solution. |
Top-end manufacturers of High quality LED's have excellent sorting and matching practises (known as "binning") to ensure even colour quality. These tend to come from Europe and the USA. The higher the binning standard the better the consistency of the LED's' colour temperature. |

It is too hard to
develop an LED
lighting solution |
Similar to other lighting technologies, like fluorescent and HID, LED's require drive circuitry, optic and thermal design to achieve the benefits of LED's. |
Top level manufacturers current technology LED lamps and associated products (eg Luxeon) help Luminaire manufacturers properly design and deliver efficient integrated LED solutions. This gives lighting specifiers confidence in the final look and effect |
| 10 |
There aren't enough complimentary components designed to work with LED's – like optics, thermal components, and electronic drivers.
|
There are presently hundreds of manufacturers offering components for LED design |
Sub-components and Luxeon light engine providers are based around the world. Certified Future Electronics Luxeon Solutions Partners can provide all the necessary components. |
