LED light bulb Q & A

Are LED bulb are rated to be used in Hazardous Condition (Class 1 division 1 areas)?
No.

Will your LED light bulb work on a Dimmer?
No, we do not recommend using our LED light bulbs on a dimmer switch, this type of switch can potentially cause damage to the bulb. Some dimmer switches do not have a true "off" position and may continue to illuminate an LED bulb when turned all the way down because LED bulbs use so little power. Unless the LED buld is specified can be used with Dimmer.

Can your LED bulb be used with day/night Photo cells?
Due to the low power consumption of the LED bulbs they do not work with all of the photo cell light controls found in light fixtures. On some models they will not turn off and with others they may blink. Because of this we do not recommend using them with a light fixture that is activated by a photo cell. It is possible for the bulbs to be damaged from the blinking.

Why some of the LED bulb does not work properly in extreme temperature?
Any temperature below 14° F or above 122 F may cause a LED bulb to flicker, dim, change color, or cease to function. Once the LED bulb is returned to an operational environment it should began to work properly. But when the LED bulb is placed in extreme high temperature, it may not be able to function even returned to an operational environment as the electronics component may be damaged due to overheating. They should not be used in an enclosed fixture with a cover over it. This will raise the temperature and kill the electronics circuitry.

What does PAR means?
PAR is also a unit of bulb measurement. In this system of lamp identification the first number listed denotes the maximum diameter of the lamp expressed as a number of 1/8's of an inch. For example, some common sizes are: PAR-38 (4.75") PAR-30 (3.75") PAR-20 (2.5")
Most of the available bulbs currently are “medium” or “Edison” base; which means they will fit into most sockets in the US.

What is the AC voltage tolerance of your LED bulb?
That should be +/-10 % if not specified. In fact some type of the latest design works from 85-260V as they have an inverter to control the Current into the LED.

Does your LED bulb emit UV lights?
No, but you should never point an LED light into your eyes. The light is very bright and could cause damage.

Why Don’t incandescent bulb last longer than it should be?
Some incandescent bulbs do last longer but there are some downsides to them. One way to make incandescent last longer is to increase the thickness of the filament so that it will not deteriorate as quickly. The down side to this is that it takes more energy to heat the filament and the filament does not glow as bright. These types of long-life bulbs typically glow an orange color. If you purchase a long-life incandescent bulb you might find that a 100 watt bulb only puts out the light of a 75 watt bulb while it consumes 100 watts. The amount of money wasted in energy with this type of bulb means you would have been better off purchasing a regular bulb.
Another way to make an incandescent last longer is to use a rare gas called Krypton gas; and no, it does not come from Superman's home planet. Krypton gas is denser than the standard gas used (Argon gas) and helps to keep the filament from deteriorating as fast. You will find that "premium" incandescent light bulbs contain Krypton gas, but unfortunately cost more money.

Can your LED bulbs be used at outdoor?
All of our LED bulbs are for indoor use only except where noted. Technically it is possible if special attention made for the dsisgn, moreover the Mine lampo are all changign to LED as for safety purposed as it has less change fot creating fire that trigger gas insider the mine!
What is the size of the screw base of the Edison base LED bulb? The size is E-26. This size works in all common fixtures in Hong Kong.

What is the proper way of dispose of used LED bulb?
Follow your local disposal procedure for electronic products with circuit boards in them.

Do LED bulbs contain Mercury as CLFs?
No.

Enjoy a Green Home Illumination using LED light bulb!

Making the most with MoSync

The latest in our series of technical papers, which bring you analysis and instruction from some of the leading authors in mobile development, comes from the team at Pragmaticomm. In his own words, John Pagonis explains what piqued his team's interest in this innovative cross-platform development tool:

"We at Pragmaticomm, after meeting with the MoSync team couple of years ago at the Smartphone Show, were really impressed with the technology and the team behind it, so we wanted to dig further. As with other companies we have been under pressure lately to bring the cost of development down while spreading across more device platforms, so we got back to Mobile Sorcery for a trial run and this is how this investigation on the Mosync SDK happened.

Our domain is Mobile VoIP, which is not ideal for such investigation, so we chose to build a mobile shopping application instead. Since this is outside our remit of projects, we thought that it would be interesting and also indicative of the problems a new developer would face on MoSync, starting with estimating the project and navigating around new APIs. We found out that MoSync was no harder than other environments and that for many domains it can really make a difference in getting your product to market when you need to cover many OSs - no matter what. Give it a go, it may not save money for everyone right now, but certainly it will be a worthwhile programming experience and for those of you that don't have the time, read on... "

Anatomy of a song

So let's say you start a band. And you put out an album. And it's moderately successful. So you decide to go on tour.

Well, you didn't think that one through too well - you've only got one album, and a few of the tracks can't realistically be done live, at least not when Dan Bejar's missing as often as he is.

Yes, you're the New Pornographers. So what do you do?

Well, you play one of the songs you've written for the new album. Even if it's not in its final form.



Compare to how the song would end up:



(Really, it's just interesting for me to listen to an earlier version of any song and be surprised at what came first. I assumed the 'introducing for the first time' line was pretty much the first thing they came up with, not one of the last.)

Cosmos Telecom Hong Kong

Friends of mine asked me where to buy my LED light bulb, I would like to tell them this Shop Cosmo Telecom.

The boss Mr. Han has been working for this lighting field more than 20 years, he is a Canadian. He knows a lot of LED. He put the best LED into his product, Xlamp, XRE, Luxeon, K2 and Seoul Semi LED...etc.

Today, a US friend of mine went there to buy another 11 pieces of 110V GU10 Warm white Lamps for his home in San Francisco. He has to buy up to 60 pieces total for his big house. I bought another two E27 3W LED bulb for my living room. The Price is less than USD15.00 each!

This shop supplies Philips MasterLED, home make LED light bulb 220V E27 screw type socket for Hong Kong domestic use. In fact his light bulb works from 110V to 230V AC.

They are constructed by three K2 LEDs and was selling at a special discount price for us!

If you are eager save more on the electic bill each month, an energy saver LED light bulb is your choice. My house uses 10 only. And by simple calculation, I may save HKD500 a year base on running LED 10 hours a day as to compare with CFL light bulb.
