CoralVue VHO Lamp Endcaps are essential components for safely operating Very High Output fluorescent lighting systems over your saltwater aquarium. These endcaps create a secure, water-resistant connection between your VHO-style lamps and the ballast wiring. Their primary function is to protect the sensitive electrical contact pins on the bulbs from moisture, humidity, and salt creep, which prevents corrosion and ensures a reliable and consistent power delivery for optimal lamp performance and longevity.

This product is sold as a convenient two-pack, providing a complete set of endcaps required to install or replace the connections for a single VHO fluorescent bulb. Manufactured by CoralVue, a trusted brand in the aquarium industry, these endcaps are constructed from durable materials designed to withstand the harsh conditions of a marine reef environment. The design ensures a snug and secure fit on standard VHO lamps, maintaining electrical integrity and safety for your entire lighting assembly.

These replacement endcaps are ideal for any hobbyist who is building a custom DIY lighting canopy, retrofitting an existing aquarium hood with VHO lighting, or performing routine maintenance on an existing fixture. If your current endcaps are old, cracked, brittle, or showing signs of corrosion, replacing them with this set is a critical step to maintain the safety and efficiency of your lighting system and protect your investment in high-output lamps.
