  1. Hey I was looking at bulbs at home depot and there were some there said they lit up multiple lumens on it. like 550/1250/2200. How does that work and are they worth buying?
  2. That means that the bulb has 3 different brightness levels, low/med/high. Lumens are a measure of light, not the color at which they burn i.e., the more the merrier.
  3. ya but how does it burn at three different levels? there was nothing to switch it with. does that mean you can use a dimmer with it?
  4. Remember when you were a kid and your parents had those lights with the switches that rotate to turn the light on and off? Remember that sometimes the light would get brighter and brighter each time you turn the switch?
  5. ya there is no point in it but if you want you can buy a dimmer switch to make use of its feature haaha
  6. so in the case of a just on/off switch relationship with the bulb it would always be at its brightest?
  7. it will probably be at the middle lumen listing, or whichever is closer to the output of the socket.

    3-way bulbs are designed for 3-way sockets.
  8. ya you would need the 3 way socket with the extra contact really its alowing you to use 2 bulbs one for low and the outher for med combine to get the 3rd full power setting
  9. Skip that bulb. A 3-way bulb only makes sense in a 3-way socket, which in turn makes no sense for growing.
