ETI LED
Frequently asked questions
Common questions about ETI LED from 3G Electric.
What voltage and frequency do ETI LED troffers support?
ETI LED troffers in the BCB series, such as the 845JZ1 (2 ft x 4 ft), operate on 120/277V AC, 50/60 Hz. This dual-voltage capability allows installation in both standard 120V commercial circuits and 277V high-voltage systems common in industrial and office buildings. No external driver adjustment is required; the fixture automatically adapts to the supplied voltage within the rated range.
Are ETI LED flat panels dimmable?
The BCB series troffers listed (845JZ1, 845JZ2, 845JZ3) are not specified as dimmable in the standard configuration. They are designed for on/off switching or use with occupancy sensors that do not require dimming. For dimmable versions, check other ETI LED SKUs that include 0-10V dimming drivers. Always verify the product datasheet for dimming compatibility before installation.
What is the color temperature range for ETI LED troffers?
ETI LED troffers in the BCB series offer selectable color temperatures of 3500K, 4000K, and 5000K. This is achieved via a switch on the fixture, allowing the installer to choose warm neutral (3500K), cool white (4000K), or daylight (5000K) without changing the luminaire. The default setting is typically 4000K unless specified otherwise.
How do I install an ETI LED troffer in a drop ceiling?
ETI LED troffers are designed for T-grid ceilings with standard 15/16-inch or 9/16-inch grid profiles. The fixture sits flush in the grid opening and is secured with clips or screws (included). For the 2 ft x 4 ft model (845JZ1), ensure the grid opening is exactly 24 in x 48 in. The fixture weighs approximately 10-12 lbs and does not require additional support brackets for standard installations.
What is the expected lifespan of an ETI LED troffer?
ETI LED troffers are rated for 50,000 hours of operation at L70 lumen maintenance, meaning the light output will remain at least 70% of initial lumens after 50,000 hours of use. This is based on LM-80 test data for the LEDs and TM-21 projections. Actual lifespan depends on operating temperature and voltage stability; the integrated driver is rated for similar life under normal conditions.
Does 3G Electric provide technical support for ETI LED products?
Yes, 3G Electric offers technical support for ETI LED products, including assistance with product selection, specification review, and installation guidance. Datasheets and photometric files are available upon request. For warranty claims or troubleshooting, contact 3G Electric with the SKU and lot number from the fixture label.
