These are some of the most favorite bulbs among the marijuana cultivators who grow their weed indoors as these bulbs provide a lot of usable light which is very good for the plants. The growth rate in the marijuana plants is the fastest when they are under this grow bulb as when compared to the rest of the bulbs. However, you do need a special type of ballast and a hood for this type of grow bulb but it is all worth it.

Types of Grow Light Bulb Sockets

  • E12

The E12 socket is also known as the candelabra. The E12 socket is the smallest screw base for a grow bulb light. The E12 socket is considerably weaker than the rest which makes it only alright to use for seedlings or clones.

  • E17

The size of E17 is most popular in the European region and in China. As it is mentioned with all the bulbs on this site, “E” is for Edison and the number which follows the letter “E” indicates the millimeter of the base of the light.

  • E26

The E26 is considered to be the standard size of the light bulb socket. The fact that it is the standard sized socket means that you do not have to install new sockets to accommodate your grow bulbs and this fact makes the E26 socket bulbs the most popular in North America. However, in the European countries, the equivalent to the E26 socket is the E27. this socket is not only helpful for grow rooms, but they have a vast array of applications which includes the general lighting fixture at your home.

  • E39

The E39 is used in North America and in European countries, they use E40. both can be easily interchanged as there is just one mm difference.

It is very important for you to keep certain things in mind when you are out looking for grow light bulbs in the market. Some of the most important factors that you need to consider are explained in detail below in our best grow light bulb review.

Wattage

One of the most important questions you need to ask yourself is that how many LED watts do you actually need for every marijuana plant you have in your indoor farm.

Spectrum

One of the questions that will definitely pop in your head is that what color spectrum will be perfect for your marijuana plants to grow into healthy plants in your indoor grow area.

Ease of use

If you are a beginner, you will want to get a user-friendly grow light bulb which will not require any over the top preparations and will easily fit into the standard socket. You will want to look for a bulb that can fit in the E26 or E 27 socket as they are the standard socket in North America and European countries respectively. However, if you insist on buying a bulb that does not fit in the E27 socket, then you will have to install a brand new socket to accommodate that grow light bulb.

Majority of the manufacturers offer warranties over them grow light bulbs but, still, there are some bulbs which comes without a warranty.
