Osram Son-T and Son-T-Plus grow lamps have been around since HPS were first used to provide lighting for plants - they are exceptionally reliable lamps and produce consistent results.
To be honest, the Sunmaster 600W dual spectrum lamp offers much better value for money nowadays, but the enduring popularity of these lamps still makes them one of our best-selling grow lighting product lines.
As with all HID lights they degrade over time and should be changed roughly every 8-10 months.
*Please retain original packaging for your lamps to validate the 12-month warranty*
