Steve I was considering led replacement for HO fluorescent bulbs. I didn’t want to wire the bypass of the ballast so I was looking at straight replacements. Outside of longer life the straight replacements did not impress me. I will give the ballast bypass type another look.

A friend who is a basement grower began with a dozen or so T5HO fixtures to get the rather high light levels he needed - expensive both initially and when replacing the fluorescent tubes (all 4 tube or more fixtures). He's been replacing the tubes with socket-compatible HO LED tubes that he found online, ballast-bypass type, one fixture at a time and after a couple of years seems pleased - cheaper and more light. Among the orchids he grows are a number of the geophytic European terrestrials like Ophrys and Himantoglossum, and he has no trouble flowering them.
