T5 and T5HO linear fluorescent lamps remain a go-to light source for high-output fixtures in gymnasiums, retail display areas, industrial workspaces, and warehouses. RelightDepot stocks a full range of T5 and T5HO (high-output) tubes in standard 2-foot and 4-foot lengths so contractors can fulfill large lamp-replacement orders without sourcing from multiple vendors.
T5HO lamps deliver more light per tube than standard T5 models and are typically found in T5HO high bay fixtures in manufacturing plants, distribution centers, and sports facilities. Standard T5 tubes are common in display cases, under-cabinet strips, and low-ceiling commercial spaces. Both types are available in 3000K, 3500K, 4100K, and 5000K color temperatures to match your existing installation.
All lamps in this category are compatible with standard fluorescent ballasts. If you are planning a full system upgrade, consider switching to LED T5 and T5HO tubes, which offer longer rated life and lower operating costs with no ballast required in direct-wire configurations. Browse the full fluorescent lamp catalog for additional tube types and sizes.
