Philips LED Light Bulb Uses Less Than 7W

- By - Source : Tom's Guide US

While environmentalists are still encouraging people to switch their incandescent lights over to compact fluorescent ones in the interest of saving energy, a new type of light bulb is just months away from the North American market.

Philips said that it will release an LED-based light bulb--dubbed the “Master LED”--in U.S. and Canada within the first half of 2009, but some media outlets have even reported that the product will actually ship in July. The product is already available in 230V countries (North America uses 110V).

The Master LED appears externally in the shape of a screw-in light bulb, and will be compatible with most lighting appliances today. According to Philips, a single Master LED retrofit bulb uses less than 7W of power and can replace traditional incandescent bulbs up to 40W, depending on the application. Of course, this means that incandescent lighting is still the way to go for situations that call for brighter conditions.

As with other LED technology, the new Master LED bulbs are estimated to last for 45,000 hours compared to just 1,500 hours for the conventional solution. Besides being energy conscious, Philips claims that its Master LED solution is lead and mercury free, making it certified green. Plus, it just looks cool.

LED bulbs have been around for a while. http://www.thinkgeek.com/gadgets/lights/9ceb/ have been selling that model for a while, and had another even before it. Interesting to see a mainstream company starting to manufacture the technology, though.

I have one that i bought at the local hardware store for use as an outdoor light. It's fine for that but the color isn't very nice. If Philips could sell a 2800k bulb with decent CRI that'd be great for indoor use.

Not impressed. Not bright enough. Maybe useful in the fridge, but that's it.
13W CFLs generate as much light as a 60W incandescent and can be found for $1 now.

Huh,what? Prove me wrong,but I could of sworn it was 120V the American's use


Nope, it's 110

Actually it ranges from 110 to 120.

It's 120. Show me a transformer that says 110.

it changes from 110 to 120 pending on what area of the country you are in. ive noticed that west america tends to have 120. not to sure about east or central though

RMS is 115. But yes 110 to 120 or in my area 75 to 170. Surge protectors are very popular.

these are too expensive !!, 40 - 100 is too much for lighting !!

I think they need more time to become affordable for average user, specially when you want something like 12 - 20 for your outdoor lighting

originally it was 110V,despite most devices show 120V.
It'll all depend on how near or far from the nearest transformer you live.
Distance often can make up for 20V.

In Europe it's the same thing; they used to have 220V, updatedit to 230V recently, though modern devices always show something like:
110~240V.

It means in a house where you have 230V on the net,peak hours can occur with 240V.

I remember someone measuring the voltage in a nightpub one day,and he mentioned the voltage was end 80V,beginning 90V!

120V is an indicator that your device can easily stand a 135V peak if necessary; and 10V overvoltage.

they been selling led bulbs on ebay for a while, but they are made cheaply and unsafe, so these philips are certified (not to short or catch fire).

I hope they work better than the led spots we've had in the bathroom earlier. The problem with LEDs is that they focus light on a small area, so they don't properly iluminate all of the area you expect. I trust philips has made the front spread the light a bit more evenly though. But who knows. I'll see if I can find some of those for sale somewhere (being european).
They should come in handy in places where you switch on and off the light a lot. You'd typically use an old type bulb for those places, as energy saving bulbs don't like it when you turn them on and off all the time. And LEDs don't really care.

Good stuff, I was an early adopter of compact flourescent bulbs, but I had mixed feelings about the mercury content in them, by the time my current bulbs start crapping out, hopefully I can replace them with LED bulbs.

I bought one 3-pak of CFLs...
Lifespan:
#1 lasted 2 weeks.
#2 lasted 2 months.
#3 lasted 4 months.

A package of 4 incandescent bulbs costs under $1. A recent test we did showed an average life of approx 6 months.

End of experiment.

You have read the article? they provide a lifespan more than 30 x your "cheap" light bulb...

the 240V level is the standard level in Australia, with actual levels fluctuating between 240V and 250V.

My experience is the same as yours. I put a bunch of those junky things in my basement (cuz I don't care what the lighting looks like there) thinking I would save money over the long haul and they just don't last at all. The box says they last for a lot longer then regular bulbs, but that is total crap. CFL's have horrible life spans, they cost 800% more and they have a "heating up" period before they really cast as much light as they say should.

I know quite a few people, including myself, that use them and they've lasted for over a year now for outdoor and indoor situations in the Northeast. When its below freezing, it may take them a minute to heat up but that's fine by me. What brand of bulbs did you guys buy because you could have gotten a refund?

Oh and what does this have to do with LED's?

Then you should try and figure out what is screwed up with your electrical system before something more expensive then a 1 dollar bulb gets fried. I have had my whole house on the same bulbs for 4 years.

after switching to cfl's i can't remember the last time i changed a bulb, i guess to put them in. nice.

Strangely, all CFL bulbs are not created equal. From my personal testing:

No name CFLs from Wally world or Sammys: Lifespan 6 months. Light, dull and ugly. More power is needed to get acceptable illumination.

Sylvania or GE high-CRI blub: Lifespan 6 years or more. Light, bright and true. Less power needed because colors aren't dull.

Try your hand with a decent CF bulb (that you might have to pay, GASP, two dollars each for!) and you might have the same luck as me. If you can't think ahead and realize that you get what you pay for, then *please* stick with incandescents; you are probably the same guys that toss CFLs and old car batteries in the trash.

I can't stand CFLs. I tried them a few years ago and the color was horrible and the amount of light was abysmal. They were of the "expensive" flavor and have since never bought them again. I use 100W incandescent bulbs most of my house and have never found an equivalent. CFLs do take some time to get to full lighting ability regardless of the temp. I am hoping for an LED solution but seems tht it's not there yet. Also, I hear that CFLs are not good to use with dimmers so that also makes them not useful to me.

CFL's have serious issues. Besides the enviromental, there is noticeable flicker with CFLs. They are very delicate, and due to their increased sufrace area, they are prone to get dirty, and are hard to clean. Also, they take a while to 'warm up' which is unacceptable for short term lighting situations. Like all FL, if you use it for a short time (a minute or less) you are effectively wasting energy by turning them on, over say, an incandecent bulb. CFL also, while cooler than incandecent, still emit significant heat, which in some situations is unacceptable. While the bulb may function for 5 years, CFLs loose their quality of light, and their flickering worsens over its life.

LEDs could solve at least some of these problems. From what I can tell from other LED sources, white LEDs flicker too. And due to their electronics on their base (AC/DC adapter, some microcircutry) they can get warm too, but perhaps less than CFLs. The color saturation is not so good on their higher lumen lights, but I don't mind the cooler shade for more lumens. LEDs also have issues with their directional light emission. They need diffusors. Finally, it all comes down to price, and right now, we don't know what it will be. If it is under 20 dolalrs, I will get one for my desk lamp (I have been in the market for a while). I just don't like CFLs, as the flickering is a significant issue. Hopefully, these LEDs won't produce noticeable flickering.

The LED bulbs hold some promise. I detest the CFLs mainly because they change the color temperature of the room (I'm work part-time in photography.) They work okay for general use and I'm all for saving electricity now that the price has doubled on me the last few years.

We have a few CFL bulbs in some bedrooms and they've lasted 2 years already. We've been in our house for just over 5 years and almost all of our bulbs are old-timey incandescent and I bet over half of them I haven't had to change yet... I'm very happy with the value they provide. CFL is fine in places where I don't put pictures on the walls.

Looking forward to the brighter LEDs to start replacing those CFLs...

Bring on the LED's and help get the mercury out of our houses. I just hope the price drops quickly. I really do not want any more CFL bulbs but I want the energy savings.

The government recommends that if you break a CFL bulb you should open the windows and then evacuate all people out of the room for 15 minutes.

Disposal of CFL's is the same as for other hazardous waste.

I really don't want to worry about these things if my toddler knocks a lamp over in the house. There are better things to worry about like the voltage on my overclocked cpu.

If you've got a toddler at home, you shouldn't overclock your pc! You won't have the time to use it anyway, so might as well save a bit of energy running stock speed when it's idling away watching you change diapers...

CRI is much more important to photography (and ambiance in general) than color temperature is. Existing LED lamps have not been shown to be an improvement over CFLs in this regard (the same issue exists with color temperature, since the bulb will cover less of the spectrum) So, what makes you think that the new bulbs are any better? Current marketing material doesn't touch on this at all.

Electrical devices require 110 volts. Going over 120 could be dangerous depending on what it is. My local company regulates voltage at 117 volts to make sure voltage never falls below 110 when someone turns on another appliance. When a heavy draw appliance is turned on it can pull the voltage down a bit and would otherwise short out other devices in your house.

If any of you are curious about your area's voltage buy a meter and check it. Check your consumption too and save power! I've got a kill-a-watt meter.

A comprable 40 watt CFL only uses 9 watts and last 10-12 thousand hours so this isn't nearly as efficient as I'd hoped LEDs would. No mercury or lead sounds good, if you drop and break a CFL you've got to run away and open ventilation!

Thank you! I was reading all those complaints about cfl, and all im thinking is Walmart special... I switched to CFL's and have had no problems but of course I did not just buy the lowest priced one and expect a miracle.
