Description
- Retrofit for existing fluorescent lamps.
- Not compatible with ballasts, requires line voltage.

Type B - Ballast Bypass: Type B LED lamps offer a cost-effective solution for your lighting needs. These lamps require bypassing or removing the ballast and rewiring them directly to line voltage. By eliminating the ballast, you not only enjoy improved energy efficiency but also reduce future maintenance costs. Upgrade your lighting system with Type B LED lamps and reap the benefits of long-term savings.
Single-Ended: This lamp requires single ended wiring to supply power. This means that the lamp will only operate on non-shunted lampholders. Bulbs are typically marked with line (L) and neutral (N) labels near the pins to indicate which end requires power.
