Q: What is an LED?

A: L.E.D. is actually an acronym that stands for Light Emitting Diode. An LED consists of a semiconductor which emits light when an electrical current is passed through it. This differs from the light that’s generated by traditional incandescent bulbs, as they use heat to make a hair-like filament glow white-hot.

LEDs are the future of illumination and their popularity is soaring, especially with the EU ban on halogen lights that’s about to come into effect very soon.

 

Q: Are LEDs long-lasting?

A: The simple answer to this question is YES! LED Monkey prides itself on providing only the very highest quality LED spotlights and bulbs and, as such, they’re built to last between 25,000 and 50,000 hours.

When compared with conventional halogen spotlights and old-school incandescent bulbs, this longevity speaks for itself, as they both have a life-expectancy of less than 3000 hours!  

 

Q: Do LEDs cost more than traditional bulbs?

A: While it’s true that that the initial cost of LED bulbs is currently slightly higher than conventional light sources, the fact that they last up to 20x longer and consume around 90% less energy more than compensates. As such, when you switch to LED as your main source of illumination, you’ll recoup your initial expenditure in no time at all.

You’ll also notice that the price of LEDs is falling rapidly, and it will continue to do so as long as LED Monkey has anything to do with it!

 

Q: Are LEDs cost-effective?

A: LED lighting is extremely cost-effective and, since lighting a home consumes around 17% of its entire energy budget, not many people can afford not to use the most energy-efficient lighting solution.

For example, an old-style 60W incandescent light bulb consumes around 44 kWh/year, whereas a halogen bulb producing the same 700 lumens for two hours per day consumes 31 kWh/year.

With a CFL (Compact Fluorescent Lamp) the number falls to 9 kWh/year, but the LED bulb can achieve exactly the same result for just 6 kWh/year. Combine this with their outstanding longevity, and you’re on a sure-fire winner when you switch to LED!

 

Q: What are Lumens?

A: For years we used Watts to measure how bright our light bulbs were but, actually Lumens are the best way ascertain the brightness of a lighted bulb or an LED lighting fixture. Lumens equal light output (brightness) and Watts are a measure of energy consumption.

With the advent of energy-efficient, low-voltage LED technology, we can no longer rely upon wattage to indicate the brightness of a bulb.

 

Q: Why should I switch to LED?

A: Switching to LED lighting brings with it many great benefits, of which these are just a few:

ü  LED is incredibly energy-efficient;

ü  It’s an eco-friendly lighting solution;

ü  With LED you’ll reduce your lighting energy expenditure by up to 90%;

ü  LEDs have a much longer life-expectancy than any other type of bulb;

ü  They operate at a low temperature, so they’re safe to touch;

ü  The light they produce is directional;

ü  They’re extremely compact and manageable;

ü  They’re far more robust than other types of bulb;

ü  Their longevity is unaffected by rapid cycling;

ü  They come on the moment you flick the light switch, with no warm-up time;

ü  Unlike other bulb types, they produce no IR or UV emissions.

 

Q: Do LEDs take a long time to light up?

A: No. Unlike CFLs which take time to warm up, LEDs achieve full brightness instantaneously.

 

Q: Will LED bulbs fit into my existing light fittings?

A: Yes. All LED Monkey’s LED bulbs have been specially designed to retrofit directly into your fittings, where they’ll replace your old halogen and incandescent bulbs. Just ensure that you choose the correct fitting/base when you’re buying them.

 

Q: Are LEDs available in different colours?

A: Yes, unlike traditional halogen and incandescent bulbs that can only emit one colour, LED bulbs and spotlights are available in three distinct colour varieties. The colour “temperature” is measured in Kelvins, and each allows you to tailor the ambience of your room differently, according to its individual function.

 

  • Warm White (2700 – 3000k) – This is the most popular colour temperature in the UK right now. It’s a mellow, relaxed colour that’s ideal for living spaces like the lounge and the bedroom.
  • Cool White (6000k) – This is a fresh, clean and clinical colour temperature that’s most often used in work-related rooms and spaces such as the kitchen and the bathroom.
  • Daylight (4000k) – As the Kelvin measurement suggests, this colour temperature lies between the other two and represents the closest possible approximation of natural daylight. As such, it’s great for close work in offices, classrooms and living spaces.

 

Q: What type of light fitting should I have in my bath/shower room or kitchen?

A: Any light fitting that’s installed in a room where there’s a likelihood of moisture or dampness should be both Fire-Rated and water resistant, with an Ingress Protection-Rating of IP65 or higher.

 

Q: What’s an IP Rating?

A: The IP (Ingress Protection) rating (mentioned above) of an electrical product, is a guide that’s used to detail the resistance to water and solid objects of the enclosure that surrounds its electrical components.

As far as LED bulbs and spotlights are concerned, the IP-Rating measures their ability to resist ingress by small solids like dust particles and liquids (usually water). The first digit denotes its ability to resist solid objects and the second digit to liquids.

An LED with an IP67 rating, for example, is completely protected against dust, and protected against water to a depth of 6 – 39 inches.

Here are the definitive classifications:

Level of Protection

Solid Objects

Q: Do LED bulbs become hot when in use?

A: LED bulbs do produce a small amount of heat when they’re switched on, but they run significantly cooler than other types of lighting like halogens, incandescents and even CFLs.

The heat they generate in normal usage is effectively dissipated by metal heat-sinks that direct the heat away from the light source. This ensures the LEDs achieve their incredibly long life-expectancy, as heat is notorious for shortening the lives of bulbs.

 

Q: Are LEDs as bright as halogen and incandescent light bulbs?

A: Yes, they are. As well as being retrofittable with the same types of fitting, LEDs are able to generate a similar number of Lumens as the bulbs you’re currently using. This makes them absolutely ideal as replacements, so you’ll never look back once you’ve switched to LED!

 

Q: Are LEDs environmentally friendly?

A: Yes, very much so!

Compared to traditional forms of lighting like incandescent and halogen, LEDs lose only a tiny amount of their energy to heat. This enables them to generate just as many Lumens, but for a fraction of the cost. Whereas old-style bulbs can squander around 80% of their energy producing useless heat, LEDs efficiently convert 90% of the energy they consume into light. This doesn’t just mean they’re better for the environment, but for your bank balance as well!

Unlike many of the old-school light sources we’ve used, LEDs contain no environmentally harmful elements such as Mercury. Unfortunately, Mercury leaked from old light bulbs has contaminated many of our precious waterways and supplies, which is one of the reasons for the forthcoming EU halogen ban.

LEDs are also manufactured entirely of recyclable materials, which means they should never need to be sent to our ever-growing number of landfill sites when they come to the end of their lives.

So, you ask if LEDs are green? Absolutely!

 

Q: What do the numbers 3528 and 5050 mean?

A: Generally used in connection with LED Strip Lights, these numbers denote the sizes of their light-emitting chips. The number 3528 means that the Surface Mounted Diode (SMD) chips lining the strip light each measure 3.5mm x 2.8mm, while 5050 means that each chip measures 5mm x 5mm.

The bigger the chip, the brighter the strip!

 

Q: Roughly how often will I have to change my LED bulbs?

A: One of the great things about LEDs is that they’re a lot longer-lasting than virtually all other types of bulb. An example of this is the LED bulb, the packaging of which states a 50,000-hour lifespan. The number of hours you have that bulb switched on each day will obviously affect the number of years it’s going to run for, so here’s a guide to give you an idea:

An LED that’s used for:

  • 24 Hours per day will last for approximately 7 Years;
  • 18 Hours per d will last for approximately 7.5 Years;
  • 12 Hours per d will last for approximately 11.5 Years;
  • 8 hours per day will last for approximately 17.1 Years.

 

Q: Do LED Monkey’s LED bulbs come with a warranty?

A: Yes, all of our LED light bulbs and lighting products are supplied complete with a warranty/guarantee of 2-years, which can be extended to 5-years when you complete the free registration.
