Replacement for SLI SYLVANIA H38JA-100/DX/MOG mercury vapor lamp, this 100 watt BT23.5 bulb delivers consistent illumination across a wide range of commercial and industrial lighting setups. Engineered as a direct match for existing multi-application fixtures, it provides steady output without requiring any modifications to sockets or ballasts. With 4100 lumens of output at a 4000K color temperature, the lamp produces a clean white light ideal for warehouses, parking structures, and large interior spaces where visibility and color accuracy matter. The 45 CRI rating ensures objects retain natural tones while the extended 24000 hour rated life reduces replacement frequency and maintenance costs over time. Facilities can count on stable operation in high-bay areas, loading docks, and exterior security zones where mercury vapor technology remains in active use.
