Installation and use couldn’t be easier:

  1. Carefully unpackage each bulb you wish to use with gloved hands (the oils of your hands may affect the use of these bulbs)
  2. Align the bulb with the sockets in the reflector
  3. When the plugs are aligned in the socket, gently turn the bulb until it clicks in place
  4. Repeat with the desired amount of bulbs, and you’re growing in no time
