This Glass Covered LED bulb features 20 individual high quality 5050 SMD LEDs that emit a light output of 320 lumen. They're intelligently designed to considerably reduce energy consumption by up to 90% and are available in both Cool white and Warm white options, compatible with both dimmable and non-dimmable applications. Using only 3.5 watts of power these energy efficient bulbs compare in brightness to a 40 watt bulb yet consume significantly less electricity.
This SMD E27 bulb features a massive 120-degree beam angle; designed to output the widest beam angle available of any SMD bulb on the market today. This bulb will install into any E27 socket with an input voltage AC175-265V and is designed for any domestic, commercial or retail installations. Using only 10% of the energy when compared to the older style bulbs, thereby offering significant savings that consumers simply cannot ignore in the long run.
Offering the latest heat-sink design, this helps to disperse any unwanted heat from the LEDs which protects the overall lifespan of the chips.
Lasting 50,000 hours compared to a halogen lamp which last 2000 hours, these bulbs pay for themselves within six months of installation. Homeowners and businesses can now go years without the hassle of having to change bulbs. These LED equivalents feature shock and vibration resistant technology, there is no filament to ever burn out or break-in, so they run considerably cooler than standard filament bulbs.
Recent advances in LED's, household electrical consumption from lighting products is being greatly reduced when using low-energy LED lighting. The Glass Covered E27 LED bulb offers consumers a cost effective SMD light bulb with all the benefits and limited drawbacks.

LED lamp energy saving comparison
Lamp colour ( Kelvins )
The colour of a lamp is defined as a measurement called kelvins. A standard GLS
light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum
and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting the
right colour temperature of a lamp does matter as the warm colour wavelength helps
to soften skin tones and gives a warm soft relaxed feel and at the other end of the
scale a 4,000 to 6,000 kelvin lamp colour would be used in offices or a fast food
restaurants to make you feel less comfortable and relaxed and more alert. There’s
nothing that can sour your opinion of a compact fluorescent or LED lamp like buying
a 4000K or 5000K bulb when you meant to buy a 2700K bulb, or vice-versa. When you
buy a new, energy efficient bulb, keep your application and colour scheme in mind
and make sure to buy the bulb with a colour temperature to match.

Light output ( Lumen's )
The amount of light that is produced by a lamp is called lumen's and the more lumen's
the lamp has the brighter it will be. Lumen's work in conjunction with kelvins and
watts should not be taken in isolation of each other, for example if you had a very
warm white lamp at 2,700 kelvins and it produced 300 lumen's and you then had another
lamp which was a cool white 6,000 kelvins which also produced 300 lumen's the cooler
lamp colour would always appear brighter to the naked eye than the warmer one this
is due to the receptors in the eye that react better to a white light spectrum. Another
factor on how bright a light may appear is contrast so if you shine a white 6,000
kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the
warmer lamp would appear brighter due to the contrast of the material it is focused
on. So when choosing a lamp always take in to account the area you want to illuminate
and think about Kelvins ( colour ), Lumen's ( brightness) and contrast ( colour of
area ) The more lumen's produced per watt the more energy efficient the lamp will
be, for example you can have a 25w candle lamp that produces 170 lumen's or a more
energy efficient 18w candle lamp that produces 180 lumen's so even though the wattage
is smaller the lumen's are greater which makes it use less electricity. That's what
makes LED lights so energy effective as they can produce 700 lumen's from a 5w lamp.
Light intensity or Light levels ( LUX )
Light levels are measured in something called LUX. Put simply LUX is a measurement
of light falling on a given surface area. For example an average LUX of 200 would
be needed for an outdoor tennis court for recreational purposes and a side street
walkway would have an average of 5 LUX. To calculate lux levels you need a very good
calculator or computer as there is a number of factors that need to be taken in to
account.Lux levels can be effected by a beam angle of a lamp, for example if you
had a 50w 38 degree MR16 halogen lamp at 3 mtrs from the floor and another 50w 10
degree MR16 lamp placed next to it, the one with the 10 degree beam angle would record
a higher lux level due to the concentrated light in a small area so you could drop
the 50w lamp to a 35w lamp to save energy and still achieve the desired light level.
