I'm not exactually an amature and know in general why stage Lekos are not supposted to be used in a residential setting besides the fact of a UL listing, however I have seven 3.5q5 Lekos - basically small 3.1/2" lensed 50degree lekos sitting in my storage closet that are my favorite babies and now have a large high ceilinged living room without any overhead lighting. I also have quality dimmers, cable and too much time on my hands. Recently on another forum a similar discussion was held involving a multi-million dollar estate and owner with far too much money wanting moving lights and I think I was the only one posting naysay points about it - specificially because the moving lights sugguested would be polyphase and I believe that's against code owing to the RF noise or something like that more than anything else given a professional install. Plan at this point is to install some pipe and drape in the living room anyway and hang a diagonal sway brace across it for stabalization. The living room windows suck and there is nothing like a good layer of stage drape to hold in the heat during winter or at least black out the evil sun. And I acquired a 10'x22' section of drape recently that would just about be perfect for two walls in addition to the rest of the more or less scrap - so the pipe and drape is a given and already laying in the living room. So I'm thinking, a HX-401 lamp has about half the output of a FLK lamp which would be about right for a small room for maximum intensity. A bit bright on a 375w S-4 Fresnel in my mind's eye memory of the output using a similar lamp and beam spread than I would like but not entirely bad. Okay, it's three times the output of an Inkie which would be even more right in output, but hopefully it's going to be used at a longer throw than a similar 3" Fresnel would be good for so it could balance out given it's going to put out about 8,000 lumens each with that lamp as opposed to 2,800 Lumens on a Inkie or 16,500 Lumens on a FLK. I would have prefered a 250w lamp but nothing is on the market anymore for that unless I traded the Lekos in for some antique Kliegl RSC small Lekos that would be unsafe. So, I'm asking the wealth, to help convince me not to install the Lekos as it would not be proper, or sure, go for it, I have similar things installed also, or ideas to watch out for. Given I'm not going to be using equipment that hasn't been brought up to factory spec, and I'll probably also install the upgraded lamp bases in them - electrically it would be okay, any other good safety reasons not to do this? I would would not recommend this for the normal lighting tech or house, but in this instance it should be assumed that the fixtures would be in mint condition and safe in general both electrically and far enough away not to cause heat problems. I have used Inkies and similar really small fixtures for years at home safely but never broke that threshold of real lights thus I'm seeking some impute before I cross it. Things like ozone issues or anything like that? Oils in the air from cooking causing un-even cooling and heat retention. Using stage dimmers on a household circuit would probably cause all kinds of phase harmonic noise that's not going to be good for computers, tv's etc. The UL rating is for temporary use of a 8 hour period, longer than that will... I'm scratching in the air for reasons. What ya think? Thanks either way on the opinion.
