Product Identity

This Satco compact fluorescent bulb uses a GX23 two-pin base and draws 13 watts to produce 800 initial lumens of soft white light at a 2,700 Kelvin colour temperature with an 82 CRI rating. It is designed for fixtures such as exit signs and desk lamps that accept a T4 twin-tube format.

Sustained Output

The lamp maintains its rated output over a 12,000-hour life span, delivering consistent illumination without the rapid lumen depreciation common in short-cycle operation. Energy consumption remains steady at 13 watts throughout the rated period, making it suitable for continuous-duty applications.

Thermal and Power Profile

Operating at 13 watts, the bulb generates modest heat that is typical for twin-tube fluorescent technology in normal indoor use. It complies with TCLP and RoSH standards, indicating controlled materials and environmental impact during operation and disposal.
