After receiving numerous requests to evaluate the large number of standard light bulb format LED grow lights available on the market, we decided to conduct a review of four of the most visible and available.
The main advantage of using this type of LED grow light is the low cost of purchase and operation, and the ease of setup. These LED lights are built in the standard format of a spotlight and fit in a standard E27/E29 screw-in type light socket. They are very easy to put into service right out of the box as you do not need any additional equipment. They have internal heat-sinks, use standard house volt/amp power, and fit in any standard (E-27) screw lamp socket.
We took at look at four of these lights offered for sale from TaoTronics, Litom, Pot Wizard, and Divine. All the lights are offered for sale on Amazon and are priced under $40.00 each.

If you look up and read through the specs and information on each of these lights you will get the impression there are four different lights offered. However, the reality is there are two lights to pick from and the selection of the right one for you, or whether you should select a different format light, is fairly simple.
The 12 watt light could be a good selection for a new grower who is only going to grow one plant, is operating on a limited budget, and isn’t sure that indoor growing is a long-term commitment. People often have a limited space to grow in or a location that does not get enough direct and reflected light to grow the plant they want in that location. The 12 watt light is a great one plant grow light for those situations. The limitation is you will need to keep the lamp fairly close to the plant (18”) and will not be able to cover more than one plants. There are three 12 watt lights ai the above table and if this LED bulb sounds like the right selection for you we recommend buying the TaoTronics lamp. They are an established company with great reviews and a good customer service program.
The other light in this format is the Litom LED grow bulb which is the same general format, but uses 3 watt LED diodes. This difference results in 36 watts of lighting, or triple the light delivered by the other three E27 format bulbs. As you may imagine this difference will result in a significantly better delivery of lighting lumens to the plant you are growing, for slightly higher price. This will be a better choice for growing applications where the light may have to be higher above the plant canopy, where the plant canopy will spread out wider, and when the light needs to penetrate deeper. This light is also better choice for plants that need stronger lighting during their bloom phase.
The main disadvantage of the E27 format LED light is two-fold.
- There is limited lighting power and spectrum per fixture when setting up a grow room or tent type setup.
- The E27 format requires you provide a mounting base for each bulb and they do not come with suspension equipment and power cords.
