Hi FN, Timer switches usually work on electricity supply and would switch off when there is a power cut or failure and switch on again once power resumes. So if there is a power cut of say 2 hours during the day and if the lights were timed to come on at say 7 pm, then the next time it would come on two hours later at 9 pm till the timer is reset. This may not be practical for Saligao, and we cannot expect our electricity department or lines men to be vigilant enough for resetting the timers, and after a few weeks the lights will be coming on during the day and going off at nights.
I have small solar lamps with light sensors (made in China) in my garden which gets charged during the day but switches on only at sunset and switches off at sunrise. Can somebody give his/ her views if this will be practical for larger applications such as street lights or the use of only light sensors (rather than timer switches) which will switch on the lights after sunset and switch off at sunrise?

That's interesting John! I think measures like these are a reflection of citizen involvement in running their own affairs -- in howsoever minor a manner. There seem to be a lot of automatic timer switches too, even for sale in India. Wonder if these would be economically viable and sustainable (meaning, not needing to be replaced every few months, as our tubelights do, apparently due to questionable tendering procedures and maybe corruption too): http://www.google.com/search?hl=en&q=automatic+timer+switches+india&aq=f&oq=&aqi= At present, because office (or temporary) staff is used to switch on/off the lights, what often happens is that they are switched on bright and early (when there's still an hour or so of sunshine left) and put off only after 7 am or so! FN 2009/12/2 John DSouza <jfdsouza2...@yahoo.co.uk> Dear FN, In some places of rural Europe, Canada and the US, all light poles have switches and the citizen living nearest or a passerby puts the lights off or on. I did this once in Utah. -- Frederick Noronha :: +91-832-2409490 ANOTHER GOA: http://tiny.cc/anothergoa Facebook: http://www.facebook.com/fredericknoronha Writing, editing, alt.publishing, photography, journalism -- This message comes via the Google Groups "Saligao-Net" group.
