Product Overview

The GE 71653 F28WT5/835HL/ECO is a full-wattage T5 fluorescent bulb designed for compatible commercial fluorescent fixtures. Its 3500K neutral-white light falls between warmer 3000K lamps and cooler 4000K lamps, while its 85 CRI provides improved color rendering compared with lower-CRI fluorescent products.

The bulb delivers 3,050 initial lumens and 2,810 mean lumens from 28 watts. Its approximately 45.2-inch tube length and G5 miniature bi-pin base are specific to the T5 format and should not be confused with nominal four-foot T8 or T12 lamps.

Rated life depends partly on the operating cycle. GE lists 20,000 hours at three hours per start and 24,000 hours at twelve hours per start when operated on an applicable rapid-start ballast. Actual performance can vary based on ballast type, switching frequency, temperature, fixture design, and operating conditions.

Compatible Applications

• Commercial fixtures designed for F28T5 full-wattage fluorescent bulbs
• Office and institutional lighting requiring 3500K neutral-white output
• Retail and general interior linear fluorescent fixtures
• Compatible rapid-start fluorescent systems
• Compatible dimming systems using an appropriate T5 fluorescent dimming ballast
• Maintenance replacement where GE product code 71653 is specified

Before Ordering – Verify

• Complete lamp code: Confirm the required lamp is F28WT5/835HL/ECO.
• Product code: Verify GE product code 71653.
• Wattage: Confirm the ballast is designed to operate a 28W T5 fluorescent lamp.
• Color: The 835 designation identifies an 85-CRI, 3500K lamp.
• Base: Confirm the fixture uses G5 miniature bi-pin lamp holders.
• Dimensions: Verify the fixture accepts a lamp with a 45.2-inch nominal tube length and up to 45.52 inches from face to opposing pin.
• Ballast: Use only with a ballast that specifically lists this lamp or an approved electrically equivalent lamp.
• Dimming: Dimming requires an appropriate compatible fluorescent dimming ballast.
• Operating temperature: GE lists a minimum starting temperature of -20°C.
• Rated life: Lamp life varies with the number of operating hours per start.
• Packaging: The GE specification lists one bulb per sales unit and 40 bulbs per standard case.
• Not interchangeable: Do not substitute T5HO, T8, T12, LED, or another 28W lamp solely because the wattage or nominal length appears similar.
