leeroy23 Posted March 6, 2007 Share Posted March 6, 2007 Hi there all, my name is Lee and im studying computer aided product design at Bournemouth University. Ok Ive only just signed up to this forum and dont know if questions laid out like a questionnaire is allowed, however if any of you could fill this out and reply to this message or reply to my email lkmason23@hotmail.com I would really appreciate it. What are the main factors you primarily consider in regards to high bay lighting? Cost Shape Size Weight Light Output Life Expectancy Low Maintenance What would be a fair life expectancy in your opinion for a high bay light fitting? 1,000 hours 2,000 hours 5,000 7,500 10,000 hours 20,000 hours 50,000 + hours If the last answer was less than 50,000 hours, would increasing to 50,000 hours be appealing? No / Yes If the answer was more than 50,000 hours, do you know of any light fittings with this capability? No / Yes________________ ___________________ ___________ How long do you feel the installation of a high bay light fitting should take? ___________________ _Hours What length of time do you believe a single light fitting should take to maintain? E.g. Cleaning, replacing lamps etc. Less than 30mins 30-45mins 1 hour 1hour 30mins 2 hours + How many times do you believe a single light fitting should be maintained? E.g. Cleaning, replacing lamps etc. Every 6 month’s Every 12 month’s Every 18 month’s Every 2 year’s Every 3 year’s + 3 year’s Is lumen maintenance (quality of light) an important factor to you in light fittings? Not At All 1 2 3 4 5 Very Much What current light fittings are you personally aware of that are available/used for high bay lighting, specifically in areas with limited access?___________________ ___________________ __________________________ ___________________ __________________________ ___________________ _______ How are these high bay light fittings fixed to the ceiling? Suspended Track Recessed Other______________ ___________________ Are these light fittings dimmable? No / Yes Many discharge fittings have a re-strike time that can take as long as 20 minutes to re-strike. Would reducing a HID light fitting’s re-strike time to less than 2 minutes be an appealing attribute? No / Yes If you own, or are aware of any high bay light fittings what is the proposed number of times a day these fittings are powered on and off? Not At All 1 2 3 4 5+ How many hours a day on average would you say these high bay light fittings are powered? ___________________ _Hours What do you believe is the more suitable kind of lighting for high bay lighting? Fluorescent HID Other Reason_____________ ___________________ _ How often the light fittings you own, or are aware of are replaced for a new scheme/refurbishment? ___________________ _Years Are there any plans in the near future for more lighting, if so how many new fittings are required?___________________ ___________ How much on average do/would you pay for installation per light fitting?£_________________ How much on average do/would you pay for a lamp replacement?£_________________ How much on average do/would you pay for cleaning per light fitting?£_________________ How much on average do/would you pay for cleaning the room containing the luminaries?£_________________ How much are your energy costs per kW/h?£_________________ Thanks again people!

Ike Posted March 6, 2007 Share Posted March 6, 2007 While some of us do undoubtedly use high bay fixtures these forums are centred around the entertainments industry (as apposed to leisure and architectural lighting) and you may therefore get more useful replies elsewhere.

gnomatron Posted March 6, 2007 Share Posted March 6, 2007 some of your questions seem ill-thought out - "Would reducing a HID light fitting’s re-strike time to less than 2 minutes be an appealing attribute?" Why would anyone say no to that question? There's no reason to. The same goes for this one; "If the last answer was less than 50,000 hours, would increasing to 50,000 hours be appealing?" Also, asking about maintenance time for a fitting is strange - surely with lighting rigged high and out of reach, the time for maintenance largely depends on the access? I can't think of any generic light that would take more than half an hour toservice. Link to comment Share on other sites More sharing options...
Dmills Posted March 6, 2007 Share Posted March 6, 2007 I would also note that the answers to a lot of your questions are highly application dependent. With good access, I would trade lamp life for energy consumption differently then I would for something that was a real problem to get to. At work the working lights (really a sort of medium bay, 30ft ish), have their actual time required to maintain totally lost in the time it takes to build the scaffold to get to the scumsucking things, I don't CARE how long it takes to service the fitting, as long as I do not have to do it often! In the paint shop CRI and colour temp is everything so we use Tungsten Halogen in spite of poor efficiency and lousy life, out on the loading bay you trade that one differently, and over the stage differently again. If there was one right answer to all applications life would be boring, you need to pick ONE application, not try to cover the whole 'high bay' gamut. Regards, Dan.

woody74 Posted March 7, 2007 Share Posted March 7, 2007 This seems like it's more of a "General Tech Chat" kind of question. My thinking is some of the "if we made a better product, would you buy it" questions are pointless (I think gnomatron said it well); it's like asking "I can hit you or not hit you: which should I do?" And from a slightly more pessimistic perspective, this seems like Lee is getting taken advantage of by someone who doesn't want to pay for market research.

paulears Posted March 7, 2007 Share Posted March 7, 2007 Moderation: The Mods agree with Woody. Although this topic is not our normal field - and perhaps this is why we seem a little confused by the content, as people have contributed we will, for the moment, let it run - but move it to the General section of the forum. If it drifts into our 'problem area' of discussion then it may have to be closed. The original poster is free to contact any of the mod team for some background information.

Ynot Posted March 7, 2007 Share Posted March 7, 2007 Hmmm... Personally, I can't see the OP getting any reasonable sort of response, as what he seems to want is the form filling in so he can tabulate results (after all, it's a uni project). What I suspect he'll get is more of the same - basic and brief freehand replies which are going to be next to useless in his context, as many questions are aimed at the purse-string holders and not necessarily the tech's who do the work.Add to that that the product is not anywhere close to the average tech's responsibility and I would say this is a no-brainer. Personal opinion, o' course. ;) Link to comment Share on other sites More sharing options...
zonino Posted March 7, 2007 Share Posted March 7, 2007 I would suggest, you would be better supplying a webpage with the form on and the ability to fill it in and press send. you will find a significant increase in people willing to complete the survey if you make it easy for them!
