Let’s get some important basics. The 32W Agrobrite Grow light you provide what you need for a small area while reducing energy costs. The 32W 6400K bulb pictured here is very bright for its size. With an output of 1800 lumens it will last an average of 10,000 hours.

Plants have been around a very long time – even before we came around. They are genetically programmed to use sunlight. While sunlight may look white, it is really made up of all the colors of the rainbow. It is only when all these colors are mixed, we get what we see as white. From that sunlight, plants use different spectrums of light to accomplish different things.

Blue light is directly related to chlorophyll production, plants with plenty of blue light will have strong, healthy stems and leaves. Blue light also helps to increase plant growth and makes the plant mature faster. Red light is responsible for making plants flower and produce fruit.

Red and Blue Grow Light Comparison

The white light emitted from fluorescent bulbs are classified into two main categories. Cool white which has more blue spectrum in them or warm white, which has more red.

Here is a picture of lettuce leaves growing under two different grow lights. Note the leaf on the bottom comes from my Grow Bucket that is using the Agrobrite cool white bulb which is bluer than compared to the leaf on top which is being grown under a grow light its is a little warmer (red light). The bottom leaf is a darker green and has a slightly more robust taste.


The spectrum (color temperature) of this bulb is mostly in the blue-light range making it ideal for seedlings, growth and maintaining growth. If you are looking for an inexpensive grow light for the flowering and fruit production suggest the Byingo LED Grow Light Bulb or HIGROW 36W All Deep Red LED Grow Light.


If you are looking for an inexpensive compact grow light for your plants the Hydrofarm Agrobrite FLC32D 6400K fluorescent grow light is a very good choice. I am using this light for my lettuce and it is performing nicely. If you are looking for a larger area to cover you will need to step up to a LED Panel or to a larger Fluorescent bulb
