Product identity

The GE 81547 is a 28 watt straight T5 fluorescent tube with a miniature bi-pin G5 base and 3500K colour temperature. It delivers 2813 lumens at a CRI of 85 and is rated for 30000 hours average life. The covRguard Ecolux coating contains glass fragments if the lamp breaks. Supplied in a case of 40.

Installation check

Verify that the fixture accepts a 45.2 inch T5 tube with a G5 miniature bi-pin base and is rated for 28 watt operation. Confirm the ballast is compatible with T5 Ecolux lamps and that the 3500K colour temperature suits the intended environment. Ensure the luminaire can accommodate the covRguard shatter-resistant sleeve.

Sustained operation

The lamp maintains its 2813 lumen output and 85 CRI over the 30000 hour rated life when operated on a compatible ballast. The Ecolux construction reduces mercury content for consistent performance during continuous use. The covRguard sleeve remains intact through thermal cycling in long-run applications.

Questions about this item

What comes in the case of 40 and do I need to buy anything else to install these tubes?

The case contains 40 GE 81547 T5 fluorescent tubes, each 45.2 inches long with a G5 miniature bi-pin base. You will need compatible T5 fixtures with G5 sockets and appropriate electronic ballasts, which are sold separately.

How do I choose between the different versions listed for this model?

The supplier lists this item as a single specification: 28 watt, 3500K colour temperature, 85 CRI, and covRguard Ecolux coating. There are no alternative versions or capacities offered for the 81547 part number.

What does the 2813 lumen rating mean for actual brightness in my fixture?

Each tube delivers 2813 lumens at 3500K with an 85 CRI. In a suitable T5 fixture, this output replaces a standard 28W T5 lamp while the covRguard coating helps contain glass shards if the tube breaks.
