tp24 strive for perfection with our honest, groundbreaking low cost lighting solutions. We vow to always put our customers first.
Understanding Watts, Lumens, CRI and Colour Temperature; in this day and age it’s more important than ever to make informed purchases, an adage especially true when purchasing light bulbs. The problem is we have to take for granted that what’s on the back of the box is right for us. Throughout this book we will touch upon some of the core concepts of lighting and lamps. For those of you that are thinking “I already know all this stuff!”, read on, you never know - you might learn something new! L1 - Most tp24 light fittings use lamps with L1 caps. This means that the low energy lamp cannot later be replaced by an incandescent or normal light bulb which would be 5 times more expensive to run! Our fittings will not accept high energy lamps. CE - With the CE marking on a product the manufacturer ensures that the product conforms with the essential requirements of the applicable European directives. CE now incorporates RoHS directives. Life Expectancy - This refers to L70F50 standard method of measurement. When most lamps have an output of less than 70% of its original lumens. (Including total failure).

What is a Lu men? Lumens are a measure of light. Ty pically one lumen is equivale nt to the light em anating from a wax candle. A conventional 40 watt light bulb would have a lumen ou tput of around 450lm. A CF L (Compact Fluor escent Lamp) with the sa me lumen output would only use approxim ately 9 watts and an LED considerably less de pending on the typ e. As a general guide the efficacy of an incan descent lamp is 10-12 lum /w, a compact fluor escent is around 50-60 lum /w and an LED ca n vary from 40-90 lum/w . Remember : the higher the lumens the br ighter the lamp.

Correlated Colour Temperature (also known as CCT) describes the appearance of the light in degrees Kelvin. It is the measure of the colour of light emitted; it can be quite yellow (2700k) or very blue white (6500k). In the UK most lamps are 2700k to 3500k.
Did you know? Some countries prefer to use lamps with high colour temperatures, particularly in Australia where 6000k is not unusual. This temperature gives off a very cool blue/ white colour.
What does CRI mean? CRI, or colour rendering index, measures the light quality of a light source as compared with sunlight (which is given the maximum CRI value of 100). The closer a light-source’s CRI is to 100, the better its ability to show true colours. Lamps with a CRI of 85-90 are suited for venues such as art galleries, retail shops and photography where showing a good colour rendition is critical. In early 2013 a change in European regulations meant that all new LED imported lamps must now have a minimum CRI of 80 for indoor use and 65 for external use.This change has considerably improved the light quality for domestic living spaces.
Incandescent or Filament Lamps: The traditional “Classic” light bulb As electricity passes through the wire in the lamp, friction is generated by the passing of electrons, heating the wire until it glows very brightly. Approximately 90% of the energy used by an incandescent light bulb is lost in the form of heat with only 10% of its output being actual light. This technology has not significantly evolved since the original designs were developed over 100 years ago.
Did you know? Thomas Edison, neither invented the light bulb, nor held the first patent to the modern design of the light bulb. In reality, light bulbs used as electric lights existed 50 years prior to Thomas Edison’s 1879 patent date. In fact, Edison lost all patent rights to the light bulb both in Britain and the United States

Halogen Light Bulbs A halogen light bulb is an incandescent lamp with a tungsten filament contained within. When combined with an inert gas and a small amount of halogen the chemical cycle deposits evaporated tungsten back onto the filament, extending the life of the bulb. This makes them more efficient than traditional incandescent bulbs, although they are nowhere near as efficient as LEDs or CFLs. Halogen lamps are generally small (G9, GU10) and generate a lot of heat so can only be used in fittings that will withstand high temperatures. Due to their size, halogen lamps are perfect for smaller light fittings though they lack the sophistication and energy saving attributes of the alternatives.
How many psychiatrists does it take to change a light bulb? None; the bulb will change itself when it is ready.

Light Emitting Diode or LED: The cutting edge in lighting solutions An LED is what’s called “solid-state lighting” technology. Basically, instead of emitting light from a vacuum (as in an incandescent bulb) or a gas (as in a CFL), an SSL emits light from a piece of solid matter. In the case of a traditional LED, that piece of matter is a semiconductor. Stated very simply, an LED produces light when electrons move around within its semiconductor structure. A semiconductor is made up of a positively charged and a negatively charged component. The positive layer has “holes” - openings for electrons; the negative layer has free electrons floating around in it. When an electric charge strikes the semiconductor, it activates the flow of electrons from the negative to the positive layer. Those excited electrons emit light as they flow into the positively charged holes. Early LEDs had quite low outputs but recent improvements have allowed for much better performance. You can now find some LED replacement bulbs for candle & spot lamps and even GLS styles equivalent to a 60w incandescent. Rapid improvements in technology will see prices eventually drop and performances consistantly improve.

Compact Fluorescent Lamps: also known as CFLs The central element in a fluorescent lamp is a sealed glass tube. The tube has two electrodes, one at each end, which are wired to an electrical circuit running an alternating current. Inside the tube is a cocktail of mercury and gases (typically argon) which is kept under very low pressure. When you turn the lamp on, an electrical arc passes through the glass tube; as the arc passes through the mercury in the tube turns from a liquid/solid to a gas. This combination causes ultraviolet light photons to be released. Our eyes don’t register ultraviolet photons, so it needs to be converted into light the human eye can register. Coated along the inside of the tube is a special phosphor powder that, when combined with ultraviolet light, creates a visible light, making it possible for manufacturers to vary the colour of the light by using different combinations of phosphors. Specifically in a ‘compact’ fluorescent lamp the tube is folded to make the lamp smaller and the ballast is normally built in so the lamp can replace the conventional light bulb.

How you can save... Typically your modern domestic kitchen light fitting uses 5 spot lamps. This table illustrates the results of using three different kinds of light bulbs for 8 hours a day, 7 days a week for an entire year!*
* Daily usage may vary for each room and each customer depending on the function and season.

From the table the significant saving from using LED lamps is obvious. What’s more, the payback for the additional cost of LEDs is only 4 months and during the long lifetime of these LED lamps, you would have needed to replace your halogen lamps many times over (halogen lamps last 10002000 hours only).

65-100 How we can help...
With a clear mission statement of providing a dedicated service for new home developers and buyers, our team has managed to bridge the gap offering easy to implement solutions as well as giving choice to a whole range of lighting options. One of the primary reasons we got into the lighting business was to enable new home owners to move in minus all the hassle of sourcing, buying & fitting their lights. At tp24 we are always working to improve performance, brightness and savings as well as making all our products attractive and desirable.
Did you know? If every home in the UK swapped 3 light bulbs for energy saving ones, enough energy would be saved to light the UK’s street lamps.
tp24 LEDs aren’t dimmable... ...but they are switchable Traditional domestic dimming is very inefficient; dimming a fitting by 50% still uses 80% of the power and can also stress your lamps. Dimmable LED lamps tend to be costly and in order to use them you’ll need to buy a special LED dimmer switch, which are extremely expensive. tp24 have developed their own solution, ‘switchable’. By incorporating switching into some of their larger, multi-arm fittings, you can now enjoy variable mood settings and balanced light reduction with 100% efficiency. Switchable fittings turn on fully illuminated but can then be switched down by up to four steps, depending on the fitting. No additional wiring is necessary and switching is operated from a standard wall switch.
Retrofit LEDs: Freshen up your lights To retrofit something is to update what we already have,without having to replace it entirely. At tp24 we can help you do exactly that. Retrofit LEDs fit straight into your existing fittings. There’s no need to replace your old ones or switch to a different cap type, just simply change the light bulb. They’re available in a range of different shapes and sizes, caps and finishes. Whether it’s a frosted candle tip with a bayonet cap, or a standard spot lamp for your kitchen, we’ve got it covered. Like the rest of our LEDs, our retrofit range is also covered by our unique two year extended warranty scheme. Simply register the serial numbers on the side of the lamp on our website, and in the unlikely event that something goes wrong, we’ll send you a free replacement
