Key parameters of 150W standard LED High Bay Light:
Model: GL-ST150W
Wattage: 150W;
Lumen : 20250lm (4000K);
Advantages of 150W standard LED High Bay Light:
1. Energy Savings
It all starts with energy efficiency – and that’s one big advantage that high bay LED lighting has over other types of lighting. Specifically, these lights use less power than other lighting styles, and it’s not uncommon for facilities to save as much as 80% on electric bills compared to lighting alternatives – potentially even more, if this lighting is combined with smart sensors.
Cost savings, however, is just one big benefit. There are many others.
2. Long-lasting & Cool
High bay LED lights last up to 10 times longer than CFL and fluorescent lights. And when they are turned on, they don’t emit any heat. This isn’t just a safety advantage over other types of lights, but because they don’t generate heat, it also saves on cooling costs. In fact, it’s estimated that facilities can save up to 20% on utilities bills, as high bay LEDs will decrease the need for air conditioning.
3. Durability & Sight Advantages
We already told you how high bay LEDs are long-lasting, but they’re also very durable – durable to the point where they’re pretty much damage-proof and essentially maintenance-free. Simply put, these lights don’t bust easily.
LED is also easier on the eyes. Turn on a fluorescent light and it’s bound to flicker – at least, for a little while. Turn on a high bay LED lamp, and you’ll get the light you want immediately. In fact, turn it on and off as often as you want – you won’t notice any problems or flickering.
4. Better Light Uniformity
It is a fact that LED lighting distributes light better than others. In fact, many report an 8% increase in light uniformity with high bay LED lighting compared to others. Other benefits of high bay LED lighting compared to fluorescent and CFL lights include lesser light distortion and minimal static buildup.
One of the main sticking points to installing high bay LEDs in the likes of warehouses is their higher up-front costs. But when you factor in things like energy savings and their lifespan, high bay LED lighting is clearly worth the investment.
FAQ:
1. Why do LEDs require power supply/drivers?
LEDs are low voltage devices. Therefore, they require a device / Power supply unit / driver, or integrated electronics that convert line voltage to low voltage in order to run the LEDs. Sometimes The driver has electronics that can interpret control signals to dim LEDs.
2. What are «cold» and «hot» lumens?
These terms do not have any photometric or engineering meaning. However, «cold lumens» is the light output of the LED chip alone when it is first switched on. «Hot lumens», refers to the light output of the LED when it is fully warmed up in the luminaire. The hot lumen value may be 30% — 50% lower than the cold lumen value.
3. Why is it necessary to use absolute photometry for LEDs?
The lumen output of a LED is dependent on the thermal management / heat sink design, the electrical characteristics such as the junction and rated ambient temperature, the driver currents, and the optical system. This means that the light output is very much dependent on the design of the actual luminaire. This is unlike other light sources like HID where the photometrics of a luminaire are fairly independent of the lamp used.
4. What is the difference between absolute photometry and relative photometry?
Absolute photometry measures very precisely the lumens emitted by a specific luminaire, while relative photometry can be adjusted to measure light distribution by various lamps with different lumen outputs. Most LEDs are permanently fixed in the luminaire along with its optics. Replacement in case of premature failure means replacing the whole luminaire and not just the light source. The lumen performance of LEDs is best evaluated, by considering the various accessories the light passes through (lenses, reflectors etc) before it falls on the surface to be lit. As a result, absolute photometry is the method usually used to measure LED performance. Note that some luminaire shave replaceable LED modules, but the same arguments apply.LED Highbay Light suppliers
