For fruiting, flowering or transitioning to flower or bloom. SunBlaster T5HO replacement lamps are the right choice when re-lamping your T5HO lighting fixtures. We recommend changing your lamps after 10,000 hours of operation to ensure maximum growing performance and results from your T5HO lighting system. Just because they look bright; doesn’t mean they grow right.
Lighting might look bright to us as humans, but plants see it differently.
