CFLs (Compact Fluorescent Lamp or 'Eco Lights') maximise production without drastically increasing temperatures or energy consumption. Although these lamps are not as powerful as HID bulbs, they are great for smaller grows, propagation, mother plants or as supplementary lighting.
The bulbs are self-ballasted and discharge minimal amounts of heat, meaning they can be positioned close to your plants. They are available in both blue and red spectrums models, meaning they are suitable for vegetative growth and flowering. Each lamp typically lasts between nine months and a year before needing to be replaced.
They are available in 125W, 250W and 300W models.
