if you drive a filament bulb with a PWM circuit it makes a great IR spot or flood light. I modded my ARLEC one, just before the filament starts to glow red seems to be good for close range, just on red is better for a longer distance.
Yeah, efficient drivers have made for some phenomenally bright lights and some very efficient ones. Someone on a flashlight forum is testing whether their Zebralight can run for 1 year in moonlight mode, off a battery not much bigger than a AA.
No party other than GSKN shall derive any rights from the Loan Agreement or have any claim to the proceeds of the Loan. The Ministry of Sustainable Development, Project Management Unit, now invites sealed bids from eligible and qualified bidders to supply of LED floodlights for St. Kitts and Nevis.
“They never go house to house and knock on the door and say ‘you need to get out because there’s danger here,’” she said.

Of course there’s a catch. In order to get fluorescence to work, you have to start with a higher frequency light—like violet or ultraviolet. But if you shine this on some materials, it will produce light of lower frequency. UV light in, visible light out.
It’s worth noting that this isn’t the only flashlight that can start a fire. Nor is it the brightest, or most high-tech. The halogen bulb is less efficient than modern LEDs, which generate far less heat. The heat created by the Mini is, in cases when you just want to see in the dark, wasted energy.
To analyze the global and key regions market potential and advantage, opportunity and challenge, restraints and risks.
The next sections of the Grand Parkway will put slightly less stress on the state’s credit card, with the announcement Friday that the federal government will lend some of the money to build the toll road.
Now LEDs are straight-up replacing incandescent light bulbs. There’s another great moment at the end of that GE video, when Holonyak’s handling GE’s 100-watt equivalent bulb. "I thought it would be clumsier," he says, and smiles. But, no, they look pretty snazzy. They’re only getting cheaper, too.
The other option is absorption. This is the process which makes rocks warm in the sun. The rocks are absorbing sunlight over time, and over that time, the energy collected into the rock will warm the surface. Any light can be absorbed, not just the infrared (heat) portion of sunlight. A terrible mirror could absorb enough light that your reflection is only a faint ghost of an image. Unless you’ve got an old filament bulb left in your lamps, you won’t notice an appreciable warming to any of your possessions, because most light bulbs nowadays are designed very specifically not to produce much heat. We can’t see it, and it’s a waste of energy to produce heat which doesn’t help us see the room.
Applicants who request that documents be forwarded in hardcopy to them must submit an account number from a local courier agent that accepts freight collect charges. The documents will be promptly dispatched, but under no circumstance will GSKN or the Project Management Unit, Ministry of Sustainable Development, be held responsible for late delivery, loss or damage to the documents.
