Frequently Asked Questions

Are these lamps compatible with SunBlaster T5 fixtures?

SunBlaster CFL lamps are for CFL fixtures, not T5 fluorescent fixtures. Verify your fixture type before ordering to ensure the correct lamp format.

How long should I run these lamps per day for seedlings?

Seedlings and cuttings typically benefit from 18-24 hours of light per day. Use a timer for consistent photoperiod control.

When should I replace these lamps even if they're still lit?

CFL lamps lose significant lumen output well before they burn out. Replace SunBlaster CFL lamps after 6,000-8,000 hours of operation to maintain optimal propagation performance, even if the lamp still illuminates.

Can I use these lamps for flowering as well as vegetative growth?

The 6400K spectrum is optimized for vegetative and propagation stages. For flowering, a 2700K warm spectrum lamp is more appropriate. SunBlaster offers both spectrum options.
