Overview
A clip base holds a pair of bulb heads on this SANSI lamp, each carrying a grow bulb in a standard E26 socket. A built-in timer switches it on and off, and it can also stand on a table.
Auto on and off at set intervals saves attending to the lamp, and a free bulb replacement is part of the warranty. The listing mixes a headline wattage with a much lower actual wattage, so plan around the lower figure. It gives a certification mark and a color temperature, but no spectrum detail.
Who it's for
People who keep a few plants by a window ledge or workbench, who want timed lighting and a clip mount, will use the heads and timer. Anyone growing in a tent, or buying on the headline wattage, should check the actual figure first.
Pros and cons
- Timer with several intervals
- Pair of bulb heads
- Lifetime free bulb replacement
- Clip and table mounting
- Actual wattage far below the headline figure
- Spectrum details not listed
- Needs a nearby outlet
Performance notes
Each head carries its own grow bulb, and output follows the actual wattage and the maximum lumen figure. The timer runs on set intervals, and the lamp works best close to the plants. Coverage should not be planned around the headline figure.
