E27 LED Light Bulb
With a 1 inch Edison screw fitting these E27 LED Grow Light Bulbs will allow you to turn a light fitting or lamp into a grow light. Thanks to their full spectrum, warm 4000k light, these bulbs are ideal for keeping house plants healthy and encouraging green growth. They are also perfect for use as a grow light when starting plants from seeds or cuttings.
These bulbs also feature a built-in timer, allowing you to set the light to be on 15 hours, off 9 hours or it can be set to be on permanently. The timer works from the moment you turn the light on, so you don't need to set the on/off periods manually.
