The bulb seems very well constructed. It has an aluminum heat seat to keep the temperature of the bulb down to a minimum. This is important for a bulb like this because it is on for long periods of time, and the heat can ruin the plants.
The bulb has 3 blue LEDs and 9 red LEDs which provide a light spectrum similar to that of the sun, which is important for the plants being cultivated.

This review is on the OxyLED Plant Grow Lights Bulb for Hydroponic Indoor Growing.
This LED indoor plant grow light is a great piece of technology for the winter months, allowing me to grow my fresh basil oregano and nana leaves indoors.
