T5 HO (T5HO) Fluorescent High Bay Replacement

A typical 4 lamp T5HO fixture draws about 234W and a 6 lamp fixture about 351W. The linear LED high bays here are commonly used to replace both, and many have field selectable wattage so you can match the light level of the old system and dial it down where the space allows. Most offer 0 to 10V dimming and sensor options.

A 6 lamp T5HO system draws about 351W. It is usually replaced with a linear LED high bay in the mid to upper wattage settings, depending on mounting height and how bright the space needs to be.

What LED replaces a 4 lamp T5HO high bay?

A 4 lamp T5HO system draws about 234W. A linear LED high bay at a lower wattage setting typically matches or beats its light output.

Should I use LED tubes in my T5HO fixtures instead?

You can, but in high bay fixtures that are years old, a new linear LED high bay is often the cleaner job. It replaces the ballast, sockets and reflector all at once and carries a new fixture warranty.
