色溫 - Colour Temperature
The color temperature or chromaticity of a lamp is usually described in terms of its color temperature or, more accurately, by its "X" and "Y" coordinates on the CIE Chromaticity Diagram. Color temperature refers to the chromaticity of a theoretical object (called a black body), that, when heated, emits light. Although no such objects exists, many metals behave similarly to a black body so that the concept can be described. For example, if a piece of iron were heated to 900°K, it would glow a dull red. When heated to 1366°K, it would change to a brighter red, and at 3000°K it would become yellow-white. At 5000°K it would appear bluish white. Absolute temperature is expressed in degrees Kelvin (centigrade plus 273°). Thus, color temperature of a light source is defined as the value of the absolute temperature of a black body where chromaticity matches that of the light source.
Correlated color temperature is the temperature of a black body whose chromaticity most nearly matches that of the light source. Because the chromaticity of a "white" fluorescent lamp only approximates that of a black body, correlated color temperature (CCT) is used. Approximate color appearance can be estimated by plotting the X and Y coordinates on the CIE Chromaticity Diagram. Note that color appearance or chromaticity of a lamp has no relation to its color rendering ability. |

Thank you fishbone and smallmo
LED was much cheaper but the color temp. were high, and it will cause higher temp. in our corridor and the glass with the floor label, am I correct?
one more thing, I wanna had somebody to clarify, does the LED bulb sultable for long term besides the high temp. problem?
also, how about the electricity usuage? which one is more energy conserve? _________________ Sal(音: 筲): 叫我Sal Sal就ok囉~ |

1. The cost of LED spot light is more expensive than the traditional spot light and energy saving lamp. As LED light is still under development. The high cost of the energy saving lamp by MO is due to the requirement of replacement of the lamp fitting.
2. As the power consuming for LED is quite low, normally less than 2W The heat generated will be very low. As LED lamps produce very little heat, it will reduce the air conditioning load and associated electric bills. This also reduces the fire hazards involved with flammable material touching the surfaces of the lamps.
3. The power usage is very low, it saves most energy.
Traditional Spot Light - 50W (normally)
Energy saving Lamp - 9W
LED Spot Light - <2W (of course, if you want a brighter one, use more LED per unit resulting higher power)
4. The major drawback is the low efficiency of the LED light. THe white LED produce only 17-25 lum per Watt, while a normal fluorescent lamp produce 80 lumen per Watt. (The higher the value, the brighter of the lamp can be produced.

Thank you Fishbone
In addition, LED limited color selection (5 color only). The cost much high than the Halogen Lamp (Quartz Lamp). So it is not suitable for the decorative use. It usually use of special effect & indication.
Type of light--------------Unit Price-------------Life span----------Power Consumption
Halogen Lamp -----------Approx. $10-----------3000hrs-------------Approx. 30W
LED ------------------------Approx. $90-----------50000hrs------------Approx. 2W
Energy Saving Lamp----Approx. $150----------15000hrs-----------Approx. 9W |

However, if you calculated per hour, we can obtain
Halogen Lamp - $0.0033 / hour
LED - $0.0018 / hour
Which in term in long run, LED is cheaper than Halogen lamp ![Laughing](images/smiles/icon_lol.gif) |
