Anyone used solar tubes for lighting?
Can’t say how they’d work in a log home…but I can comment on how well they function in our workplace. Except for my office which has one small 12” x 36’ window up high the rest of our building is a concrete cave – no windows, thick concrete walls, the overhead is a ‘classic’ drop ceiling which hides the heating and air conditioning ducts, electrical conduit, fire sprinkles, etc the space a rather large a U-shaped maze of 20 cubicles and 8 offices. About 36 months ago Facility Maintenance installed solar tubes. Most of them were installed near or over people’s work spaces with some in the main aisle ways. They work incredibly well. They have at the lower end an opaque/frosted lens which diffuses the light nicely – otherwise sitting under one would be like being below a magnifying lens. Prior to installation our only lighting was overhead fluorescents. If we had a power outage it was totally dark, you couldn’t see you hand in front of your face. The solar tubes literally make a night-and-day difference. On many days we don’t even turn on the lighting. Ours have remotely operated internal diaphragms similar to a camera lens which allows each tube to be adjusted to allow more or less light. I’d strongly recommend this feature especially for those hot summer days or conversely when they allow more light on a cloudy day. I had thought about using them or skylights when we build but was not sure about sealing the roof to avoid water leakage. I had thought that and alternative would be to put large windows at each eve end by the ridge poles, figuring that there would be enough light during the day but I honesty don’t know how well that works. Actually that is a question I had been planning to ask someday on one of the forums. The solar tubes here at work were professionally installed and have never leaked. Our roof is very low pitched so run-off and leaking was a problem before they re-roofed a few years ago. They say it never rains in Southern California, but LOL like the song says, “when it rains… it pours!”

We have 3 in our current home and love them! Nice and bright and work well (of course when the sun is shinning!) But even on a cloudy day, they provide some light. We have one in the laundry room, guest bathroom and hallway. On bright days, there's no need to turn the light on. I'd like to incorporate some in our log home.
RPM did you install them yourself? or hire someone? They don't appear that difficult. I am not a construction expert but I'm a huge DIYer.Originally Posted by RPM
Solar tubes are a fairly straight forward install. just make sure that you have a good seal on the roof. I have installed several on comp shingle roofs and all haveworked out great and the light they provide is awesome.
That's the feeling I get reading about them. Install is very doable for a DIY. Good to hear feedback from someone who's done it!
very doable and yo'll love them ---- if putting into a steel roof it's a bit more work and you may be limited in the sizes you can implement but it doesn't take much to brighten the whole place up. The flashing and gaskets used to do a SS seal just needs to be carefully done. I've done them on a total of 7 places now for myself and friends and family and they rock as my son said !
I guess the hesitancy I have, and remember I'm a novice builder, is hearing from many, "the more holes you have in your roof the more chances for leaking". I really like the idea of solar tubes though for lighting. I'd like to think during the daylight hours we could get away with extremely limited artificial lighting.
After taking the class I would go with a regular skylight. The shallow roof depth negates the need for the tube and diffuser that the solar tubes use, they work great if you have attic space but not a vaulted ceiling.
Holes in roofs are fine, but I'm wondering if they could wait til the place has been lived in for awhile. It would be a shame to brighten up a place before knowing if it was too dark or not. I can't help but think of that Acura we loved so much. It had a tinted glass sunroof but the best part about the sunroof was that nice little screen that we could pull forward to keep the sunlight from basking all its glory on us. Too bright can be a pain in the eyes.
