iGloEZ Set of 2 Grow Light Adapter - fits All AeroGarden6 and AeroGarden7 With this adapter: 1. You don't need to buy expensive original light bulbs for your AeroGarden. 2. You can buy good brand full spectrum (daylight) grow light bulbs much cheaper in the marketplace and make them usable in your AeroGarden. Screw the standard E26/E27 light bulb into this adapter, and that's it. You can now plug it tightly in AeroGarden and use it for your plants. Please note: Due to the size limitation inside of the AeroGarden lamp hood, it would work only for light bulb no larger than the size of 2.2" x 2.2" x 5.6". (Please refer to compatibility chart to see if it fits your AeroGarden model.)
