I just came across this in the back of a Keichler lighting catalog. Hope it is useful to you. The question was, How much light do I need in an area to light it properly? A - Multiply the length times the width of the room. Then, multiply that number times 1.5. That give you the amount of wattage you neeed to light the room properly for general illumination. Example: A room is 12 ft. x 16 ft. (12x16 = 192) Then multiply 192 x 1.5 = 288 watts. For specific task lighting in areas where stronger light is needed, multiply the area's square footage by 2.5 rather than 1.5 to find the needed wattage. These same rules apply to every room or area in your home.

Hmmm, You're supposed to choose the lamp, then the trim and housing to hold the lamp you need. Not the other way around. 10' ceilings require that the lamp be tucked up in the housing to reduce glare. Fixture spacing is determined by the lighting you need and the beam angle of the lamp. You should try the 206 trim with a Philips 60 watt par 30. Beam spread & wattage depends again on what you're doing with the light. The link takes you to the choices. Here is a link that might be useful: Philips

I appreciate your replies. I have been rereading them to absorb as much as possible from your recommendations. A couple of comments: Shannonplus2, you have renewed my interest in 5". I thought I could only go up to a r20 in 5" but after your post I found I could use r30s, so there is no reason to go with 6"...still checking this. You are the second person who mentioned Alzar. I really want to see them to understand why everyone likes them. The "clear" got me. Are you saying the highly refective is good. I tested one and found it really shot out the light, but I was using a pretty strong bulb. Janwad, If I use a cfl, the watt (65) restriction doesn't really affect me because even a 100 watt CFL only uses 23 watts. The real issue is how much heat the ballast on the bottom of the bulb can take. In a can the heat , although a fraction of that produced by other bulbs (except LEDS) might become too high for the CFL. I tested the heat on 3 spiral CLF bulbs and compared them with the manufacture specs. None passed. The heat was not high, but it was too hot for the ballast. I spoke with bulb manufactures about this. One even told me to drill holds in the can at the top to get the heat out. Of course there should be no insulation contact. The bottom line is only CFLs that are authorized for recessed cans should be used. The can thermal switch might not trip because the heat is low but the ballast may stop working. I found 2 cfl bulbs that get the light I want that I will be trying, that are OK for recessed cans. One is $32 (and it is not dimmable; the other is a $23 dimmable. Both give 1100 lumens. Thanks for the info about the fixtures you have. Maria and coffeehaus, thanks for the info about the LEDS. Fern4, Sam's also now carries LEDs. Check the lumens and color. The Cree gives 650 lumens, can be purchased in standard 2700k and, my preference because of a white kitchen,the 3500k. The CRI is 92 which is amazing,it is supposed to go on instantly and is dimmable to 25% (but I don't know if it needs a special dimmer). But darn is it expensive, but it should last a very long time. Alot of manufactures are working on LEDs on. I may switch if the price goes down. Here is a question to you Cree owners. It appears that the trim and reflector is built-in. Is that correct? That could save money which would help justify the bulb. Thanks again for your posts. Bob

I have Juno and I really like them. Make sure you look at the features, which I didn't know to ask about but I lucked out anyway. Ask what types of bulbs you can use, if they are compatible with CFLs should you decide to go with those in the future, even if you don't intend to now. They are getting better all the time. One feature that came up here was someone who felt hers were too glaring and I was able to fix that on mine by recessing the bulb deeper into the fixture, but they do need to be adjustable that way, and I am not sure if all of them are. So, the more versatile bulbs you can use, and fixture and dimmer that are also compatible with CFLs (I like to have options), a variety of trim pieces available so you can alter/update the decor if you want, and a fixture widely adjustable to recess the bulb or make it flush with the ceiling depending on your lighting needs and comfort.
