LEDs or incandescents? |
I'm not sure exactly what these bulbs were but they might have been something like these 3W (equivalent to 40 W) warm white LED candle shape bulbs. There were 10 in each chandelier and there were at least four in the room. Using incandescents that would be 1.6 kW. With LEDs it comes to 0.12 kW. The lights were probably on at least 12 hours a day, through eight months of the year so each individual bulb (costing £5.99 from Amazon) would save the pub around £1.30/month and pay for itself in less than 5 months.
What about LEDs at home? You are unlikely to have the lights on so much of the time - say 3 hours per day - but you pay more for your electricity - probably 14p/kWh compared to 10p/kWh for the pub. So, a similar exchange of bulbs, 3W for 40W, would pay for itself in 13 months.
If you've been holding off converting to energy saving light bulbs because you don't like CFLs then maybe now is a good time to consider LEDs. (For a comparison of LEDs and CFLs see Should I buy LED bulbs?)
Or, if you want to hang on a wee bit longer and you don't mind using a little extra power to get something that will totally fool your friends, Philips have just announced a new bulb with special optics to make the LEDs look just like an incandescent 40W bulb, and it is dimmable as well. It uses 6W rather than 3W and they expect it to cost €8.99 which is around £7.40.

ReplyDeleteNow there's a lot of LED Bulb are make in the way they act like incandescent bulb, so we can hardly find out it is a LED bulb or a incandescent by the first sight.

ReplyDeleteI am encouraged to switch from traditional light bulbs to more efficient Energy Saving Light Bulbs. Energy efficient bulbs do not waste so much energy on heat. There are a number of different kinds of low energy light bulbs available, including compact fluorescent light bulbs (CFLs), Light Emitting Diodes (LEDs) and fluorescent bulbs or tubes.

ReplyDeleteI think some technology and other energy management resources have proven to be incredibly helpful and beneficial to many enterprises and organizations, finding the right technology that accurately captures energy consumption and provides useful data for smaller buildings has been a challenge for smaller businesses. As a result, many small businesses have relied on others, such as their HVAC contractors to manage and oversee building energy efficiency. Energy management system Texas
