3 40w or 6 23w?

  1. which setup would produce the least amount of heat? I am thinking or making a space bucket but I'm not sure if there would be a difference in heat produced by three 40w cfls or six 23w cfls.
     
  2. "Personally, I prefer to have lower wattage bulbs as they put out less heat and thus can be put closer to the plants. I use 7 23 watt bulbs, 4 goofy 13 watts (just because I have the socket space) and 1 43 watt bulb. I've never had any problems with the 23 watt ones, but I have gotten heat stress from the 43 watt bulb being too close to the plant. Also, with having multiple lower wattage bulbs, you can play around with the light spread and if one of those break the cost is far less to replace than a 150-200 watt cfl.

    a bigger bulb is more efficient, however, in the grand scheme of things we're only talking about a handful of watts being saved which isn't much when you look at the big picture."

  3. I get that lower watts produce less heat but I need to know if two 23 watt bulbs produce more or less heat than a single 40 watt bulb. I am thinking of making a space bucket and want to keep the heat minimal.
     
  4. Also, I would be using 12 gallon buckets instead of 5 gallon.
     
  5. go with the 6 23w. Heat won't be a big issue with CFLs anyway, but they have horrible penetration you will get more use out of having more light sources close to the canopy.
