LED High Bay FAQs
What is the advantage of a linear LED high bays?
With so many types of LED high lumen options on the market, it’s best to explore and compare the best fixture for your application. What are you willing to accept in regards to price, performance, and the cost maintenance? All factors to consider. For warehouse, production and manufacturing facilities, the most popular options is the LED linear high bay.
Available in 2, 4 and 8 foot lengths, linear high bays combine better light spread for maximum distribution and higher efficiency for increased energy savings. It typically requires less fixtures to achieve desired light levels. Linear high bays are also easier to maintenance, highly sustainable and may be upgraded for retrofit in the future. They should not be considered as throw away fixtures when drivers and diodes reach end of life. Linear LED high bays are ideal for large open spaces, work areas, storage aisles with racking, cold storage, and gym lighting.
Why is internal heat a factor with LED High Bays?
Extreme heat within a high output fixture can cause gel capacitors to dry out inside the driver components. In turn, this causes premature driver failure long before the end of rated life. A well designed high bay should be constructed of aluminum (superior to steel for heat dissipation), vented for heat escape, and provide adequate heat sink to absorb and disperse heat away from LED diodes and drivers.
Is glare an issue with LED High Bays?
Yes. LED high bays typically require lenses to diffuse glare. As a general rule, lens diffusers should be used for low bay locations (below 15′) as well as high bay locations 15′ to 30′. In higher applications a lens may not be necessary. It also depends on the sight line of the fixture and the application. In many cases, lighting manufacturers will base fixture efficacy on open fixtures without lenses. This is excellent for stating high LPW (lumens per watt), but may not be suitable for the needs of the application. Accurate lumen calculations need to be addressed with and without lenses for the best measure of performance.
What’s the difference between fixture efficiency and fixture efficacy?
Fixture efficiency is calculated by the amount of light produced by the light source within the fixture vs the total amount of light emitted by the fixture. Fixture efficacy is the measurement of useful light output per unit of electricity. This is calculated by dividing the total lumens emitted from the fixture by the total wattage consumed by the light fixture…lumens per watt (LPW).
Do I need to match lumens when replacing T5, T8 or Metal Halide high bays?
Typically with LED high bays, you may decrease rated lumens by 15% to 30%, possibly more. T5 and T8 high bay ratings are based on system lumens not actual fixture lumens. Fixture efficiency is not stated up front. LED high bay testing accounts for both fixture efficiency and efficacy (LPW). A quality T5 or T8 high bay should have a fixture efficiency of 85%, so a 4-lamp T5 high bay stated at 20,000 lumens is actually producing 17,000 useable lumens. Couple that with higher color rendering (CRI), and broader spectrum light, LED’s, in short, provide a better quality lumen for higher visual acuity. To eliminate guesswork, the the most accurate method for determining light measurements (foot-candles) and the lumens needed per fixture is to prepare or request a photometric lighting layout using credible IES files.
Are 1st Source LED High Bays Dimmable? Controllable?
Yes, all of our high bays have low voltage dim to off capability built into the driver. Fixtures may be prepared with dimming leads to run low voltage wiring to a dimmer switch or may specified with line voltage dimming drivers. Integral control sensors may be added to the fixture to control on/off for occupancy or configure desired dimming levels. 1st source also offers wireless control systems that may be controlled by a PC or hand held device. In addition, emergency battery back up drivers may be installed in our fixtures at factory. Consult our factory for details.
