I guess that is what government is trying to promote here too right regarding CFL light bulb. It even gets printed on the electricity bill :) I heard from the month "magh" if you buy a CFL you get another one free!?
LED light bulbs are great alternates but for low intensity lighting purpose only as (i feel) the light is very annoying. I bought a few LED emergency lights from the market. Great alternates to anything costly. They claim 40-50 hours of continuous lighting / full charge. Good lighting. Also, yesterday I call up someone in the related field and he said me, to power up a average Desktop computer with a CRT in battery backup for ~ 3 - 4 hours it should cost you no more than Rs 20,000 70 Ah battery - 9800 Rs 10 AH transformer (battery charger) - ~ Rs 4000 Other circuitry ( voltage regulation, overload protection, circuit breaker) ~ Rs 2000-3000 wiring, bulb, switches - Rs 1000 ( for home lighting ) Rs 2000 - 3000 extra, (get a bigger AH battery ?) Design Restrictions: Charging time no greater than 3 hours (will severely reduce battery life / increase some maintenance cost) Designing the system under ~10K may be possible (using ~40-50 AH battery )but it may only give backup power for 1-1.5 hours. I found the 10K solution is the most cost effective if you just have to charge adapters (buy a DC mobile adapter) and use the DC for lighting. (You get DC light bulbs in the market as well) Market price of the equivalent would likely be double or more than the cost price of the parts and assembly. Please consider to put some of your experiences........ how are you solving your lighting/power problems? Are we going offtopic :) lol regards, -bipin --~--~---------~--~----~------------~-------~--~----~ FOSS Nepal mailing list: [email protected] http://groups.google.com/group/foss-nepal To unsubscribe, e-mail: [email protected] Community website: http://www.fossnepal.org/ -~----------~----~----~----~------~----~------~--~---
