I don't have that issue yet, but in contrast to jellytoast's post, someone else posted recently that she switched from warmer to cooler UC lighting and was thrilled with the change. I think it's personal preference. Whether cool goes with warm and vice-versa, I can't say.

Hey all, It's about time for me to bring in my plants (focusing mostly on broms) for the winter and I need to replace many of my t5 bulbs. I'm wondering what would be the best color temp to get. The aim is to focus on good, solid growth, get/maintain leaf coloration and just generally keeping the plants happy until they can go back out next summer. Does the spectrum affect the coloring up of the leaves or just the intensity? Does anyone have any insight into the 6500k range vs. 5400k? Anyone have any experience or heard anything about AgroMax's Pure Par bulbs? I'm wondering if the benefits justify the extra cost. Thanks in advance, Bob

Light color temp is a personal preference. personally I like the cool lights. I have them in every room. They are the closest to sunlight. I love the windows in my house flooding in the natural sunlight during the day and want a light that can get as close to sunlight in the evening. I don't find them harsh at all, but cheerful. IMO everyone is use to the old warm lights and aren't use to a bright lights.

Michelle misses Sophie, air leakage from a can light into unconditioned space can be mitigated. My attic is directly under my living space, and my house came with about five recessed can lights from the 70s. I had the Energy Star program in to seal and insulate my house, and as a part of the program, they put these big styrofoam buckets over each recessed light. That way, air movement is stopped from moving from living to unconditioned space. In my state (MA), any contractor that comes after the Energy Star program is required to insulate their work to Energy Star's standards. I'm not at all worried about putting can lights into my upcoming kitchen reno.
