Study: LED lightbulbs make people feel safer

[one...two...tree 2,762]

New lighting technologies aren’t only more efficient - they can create a social benefit. Brighter LED lighting in public spaces can affect how secure people feel while strolling empty corridors and stairwells after dark, according to a study.

Energy Saving Trust, a non-profit jointly funded by the UK government and utilities, last week published the outcome of a multi-year LED lighting pilot throughout public housing complexes in the UK. LEDS replaced incandescent light bulb.

It learned that LED lighting has the effect of making people feel safer than Edison’s bulb. Tenants observed that LEDs were “fresher and bright,” and more similar to daylight, thus providing a more positive sense of security, an Energy Saving Trust spokesperson told BBC News.

“The increase in colour temperature typically produced by LEDs also improved the environments monitored in the field trial, a factor much appreciated by the social housing tenants,” the report’s authors wrote.

Housing authorities are estimated to have saved nearly 3,000,000 kWh of electricity by making the transition, and also incurred lower maintenance costs due to the LED technology’s considerably longer lifespans. The pilot also reduced carbon emissions.

Of course, residents did not bear the cost of the upgrade as a homeowner would. It would likely take a typical household much more time to receive payback on their investment in energy efficiency than a housing complex.

However, given the outcome of this study, it’s striking how a popular movement of laggards insists on resisting upgrading lighting technologies in the “new world” while the “old world” is primed to move ahead. Economies of scale happen, and manufacturers are heavily invested in the transition.

Is the incandescent lightbulb made from bald eagles?

No. I can buy an incandescent bulb for $0.70 and I have to pay $5.70 for a more "energy efficient" bulb, which doesn't equate the proper savings on my electric bill.

It's really that simple.

The problem with the newer bulbs is they are being shoved down people's throats and not gradually phased in.

You didn't need to shove LCD TVs down people's throats, they saw the quality. You didn't need to shove ipods down people's throats, they saw the quality.. Same with CDs, DVDs, etc...

If pig-tails and LEDs are great, they will sell themselves. It's really that simple.

insulting yourself in posts again?

Self-hate really isn't healthy and leads to suicidal tendancies. You should really get that checked out.

It all depends. There are some local programs sponsored by electric companies that will give rebates on energy efficient bulbs and fixtures. They also do this with energy efficient appliances. My electric company offers some:

In my experience, these bulbs often last longer as well. So it may even out. In any case, it is a huge difference at the register if you don't have any rebates or coupons to lower the price, I totally agree on that. If they evened out the prices, I'm sure a consumer would spend the little extra to get a longer life & to lower their energy bill.

In the winter, a higher efficiency bulb doesn't lower your energy bill. All the energy that is wasted becomes heat. You are paying to heat your house anyways. If you leave the lights on, the heat will run a little less. It's not much less. But that's because the waste heat from an incandescent light bulb isn't that much. I may switch to LEDs in the summer, but in the winter, it just doesn't make sense.
