400W LED high bay light is selected by University playground

Many university playground lamps are obsolete, and TEK Lighting recently replaced its original golden halogen lamp for a university, instead of using LED stadium light. A part of in order to save money, and part of the reason is that brightness can achieve basic lighting requirements, in order to students health.

In the past , people in the use of lamps and lanterns can produce two big mistake.

First is everyone always thought that the greater the power, the higher the brightness, but the actual brightness is depends on power and luminous efficiency. On the basis of same power , luminous efficiency is higher, the total luminous flux is big.

Used golden halogen lamp, after secondary light distribution of lamps and lanterns will loss a large part (loss: about 50% of luminous flux), combined with infrared and ultraviolet (uv) content (about 20% -30%) .

And TEK lighting LED stadium light, using good quality chip, the single side of the light, through the professional lens to disperse the light, basically the light does not wear out. Photoelectric detection report shows that the luminous efficiency of LED stadium light is greater than 100LM/W. The total luminous flux of the 400W LED stadium light is about 40000LM.

People also believe that compared with LED stadium light, the price of golden halogen lamp is relatively cheap, based on the requirement of brightness. 

Take a lamp for example, each lamp works 10 hours per day, 0.8$ per hour calculation. Compared with the above electricity fee, a 400W LED stadium light can 3 months to reach return on investment from the golden halogen lamp, which has not been added to the maintenance cost of golden halogen lamp, and the bulb will be damaged and replaced.
