OttLite 20EDG2R 20w Plant Grow Bulb
You Can Fool Mother Nature! Bring the best in natural lighting to your indoor plants. Developed by Garden Club of America award-winner, Dr. John Ott, OttLite Natural Light Supplement lighting provides the benefits of natural daylight without the damaging effects of heat so it won’t dry out soil or wilt blooms. The output of a 20 watt OttLite bulb is roughly equivalent to that of a 75 watt incandescent bulb. So, they use about ¼ the amount of energy for the same amount of light. However, it's not just about energy-savings, it's also about the quality of the light.
