        Has anyone noticed what the effective distance is? Could I put two of these in the ceiling fixture in my room and have the bulbs actually benefit plants near the floor or would that be too far from the bulbs?

        Answer This Question

        Thank you for your question, the distance between the bulb and the plant , if they are high light plants should be 6 inches on the seedling stage through the first 2 weeks and from 16-30 inches on the vegetative stage/or flowering stage , if low light stage should be 12 inches on the seedling stage through the first 2 weeks and from 24-30 inches on the vegetative stage/or flowering stage

              When growing flowers, at what point do you switch the setting from seed to seedling TO vegetative with the adjustable grow light?

              Answer This Question

              You can leave all color settings on.The plants will grow just fine. Plants outside get full spectrum light from the sun, not just red or blue etc.

                Thank you for your question, the amount of distance and time used all depends on the type of plant being grown. High Light Plants (such as tomatoes, peppers, perennials, etc) would benefit from 6” distance during the seeding stage, and a distance of 16”-30” during vegetative/flowering stage. Low Light Plants (such as basil, lettuce, etc) would benefit from 12” distance during seeding stage, and a distance of 24”-30”

                    would an ELV dimmer or even a standard dimmer (potentiometer) work to control light output?

                    Thank you for your question, sorry this light bulb is not dimmable, therefore it would not work with any type of dimmer.

                      Light caught fire internally
                      My light caught fire internally and stopped working. The switch lever fell off after the flame shot out for a few seconds. I reported this product defect to Home Depot and they couldn’t care less. I would not recommend this product.

                        great bulb
                        This Selectable Spectrum bulb for Seeding, Growing, Blooming indoor planting really impressed me. I've been trying to grow seedlings indoor over the winter time. Obviously light has been a drawback being in the dark indoors. This bulb gives a spectrum of light which really helps the seedlings flourish. Its still in use and hasn't burned out, I really like this light bulb.

                        Versatile but not like the sun
                        This grow bulb is convenient because it fits into any standard lamp or fixture with its A26 socket base. The three different light settings are easily changed with the slider on the bulb, although the spectrums do not represent real sunlight in any capacity (more below). It’s economical to save on wattage with an LED since it must be on many hours every night. This one is 9-watts, therefore equivalent to a 60w incandescent in brightness at ranges of 600-900 lumens, which is not near as bright as the sun coming through a window, but certainly better than darkness at night. This bulb should be placed near the plants as they can take much higher lumens.. into the thousands for ceiling lights. For color spectrum analysis, I included graphics showing the intensity color wavelengths of natural sunshine in various sample times of day and locations, against those for each of the light settings on this bulb. You can see that the bulb lacks color intensity throughout the spectrum, except for blue which is high on all three. It is especially lacking in the 500 range (turq. to green), which humans might not see, but I’ll bet plants do and probably miss. This bulb represents norther hemisphere sunshine (cool-blue) rather than near the equator (more balanced) where most houseplants natively grow. I’m not using the blue seedling light since it is almost the same as the white grow light, but less intense. (This bulb is already low intensity.) I use the red flowering light evenings, and the white grow light overnight, to give the plants an overall more balanced light spectrum closer to what they would get from the sun. The houseplants do not turn toward any of the light settings overnight, yet they do turn toward the window during the day. I’ve only had it a few weeks and haven’t noticed any marked increase in growth in my plants, but I am certain it hasn’t hurt. Time will tell.

                        amazing versatility
                        This is an amazing grow light bulb. The switch on the bulb itself allows you to select the right light for either seeding, growing, or blooming indoor plants. I've never found a similar bulb elsewhere. I really hope that this will help with winter seeding and growing before it's time to put plants out in the spring. The instructions show it used over a hydroponic system, but I hope it will work with my winter growing.

                        great LED grow bulb
                        This Feit Electric 9-watt selectable spectrum grow light is great for your plants indoors. The regular base allows you to use it in any standard light socket. The bulb can provide the spectrum of light needed for a variety of plants at one time. You can select the spectrum needed for you plants. Being an LED bulb, it will save on electricity and will last a long time.

                        very exciting innovation
                        with this bulb comes the ability to turn any old light socket into a grow light. it is so cool. i have a basement closet that we are going to try growing some small plants over the winter so i wanted to give it a try. as far as i can tell it will work great. there are 3 different light settings, blue, white and red, for seeding, growing and blooming, so it’ll cover the whole life cycle of the plants. the greatest part of all of this is it’s a 9w bulb which is absolutely insane. it is very bright and functional for a 9w bulb. so while i have some experimenting to do i’m very satisfied with the bulb itself and i’m looking forward to finding my green thumb.

                        The Feit Electric 9-Watt A19 Selectable Spectrum for Seeding/Growing/Blooming Indoor Greenhouse Plant E26 LED Grow Light Bulb works great!! It looks like a regular lightbulb so it fits any socket. It has a switch so you can change the settings from blue to white to red. This is more geared for flowers and vegetables but I use mine for house plants.

                        Let there be Light(s)
                        I like that this bulb doesn't require a lot of space and will be using it mostly for cultivating seedlings and an indoor herb garden. Being able to put this into a simple fixture and point it where it's needed is a huge plus.It produces wavelengths along the breadth of the growing spectrum, and is switchable between, (mainly) white, blue and red, for the different growing cycles. It's really clever actually and is made possible by advances in LED light technology. The PAR of 29 - which measures the actual 'light intensity' (or the number of photons that the bulb produces), is what you would expect from a single bulb - supplemental, targeted light mostly suitable for houseplants, herbs and seedlings. Very cool.
