The full-spectrum 25-watt output is incredibly bright. It can be considered equivalent to a 150-w watt conventional bulb of yesteryear. The light panel is large, measuring 8. Inches.

Unit as a whole is lightweight and easy to maneuver. Utility is relatively high. Allows you to put a tray of plans directly over it. Shipped fast & in great condition.

The base is stable enough to balance the fixture unless twisted into an awkward position. At full extension ( as in the photos ) as you tilt the light, it wants to tip over. The extendable pole holds it very well.

The most stellar feature of this light is - the controls. The daisy chain feature is great as you only have to plug one into the outlet. Plant seems to be adapting to this light pretty well.

Sturdy tripod and lighting head appears well made. It's very sturdy and heavy so no worries about it getting easily knocked over. The telescoping stand is also very nice.

The gooseneck and clamp that it's attached too is far too flimsy to hold it. Also, the goose neck is extremely short. It's hard to clamp it to a table without the head of the light being right up on the plant.

Vipar spectra is a great light for indoor gardening. The fixture is easy to attach to terrariums. The light is bright and cheerful on cold rainy days.

The dimmer is awsome. The adjustment knob works smoothly and it is attached solidly. I love the dimming knob, though it does not turn the light all the way off.
