Pros
- One of the cheapest ways to light a 2x2 ft seedling or herb tent
- Dimmer knob lets you turn it down for seedlings and up for fruiting plants
- Fanless, so it runs silently in a living space
- Plugs into a Spider Farmer GGS controller for scheduled dimming
Cons
- The maker’s own output and efficacy figures disagree, so its real efficiency is likely closer to 2.2 µmol/J
- Too little light for more than a 2x2 ft area of fruiting plants

#5 in Under 300 WFull review
A quiet single panel for a 2x4 ft tent or a seedling shelf. Choose it for its simple build; a bar light gives more light for the money.

#7 in Under 300 WFull review
A light, quiet panel for a 2x2 ft tent of seedlings, herbs or leafy greens. Good value for a first grow, though bar lights use less power for the same light.
