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 or Double-Ended: This lamp offers the flexibility to be powered in single or double ended wiring configuration. Meaning the bulbs can operate on shunted and non-shunted lampholders. Bulbs are typically marked with line (L) and neutral (N) labels near the pins to indicate how to wire the sockets.
