Why LEDs?

As a rule, LED bulbs use 90% less electricity than standard bulbs. They have an unparalleled even spectrum of light and have a lifespan beyond ten years. LED’s provide us the most efficient way to save energy and conserve our natural resources. Less maintenance, environmentally friendly, lesser CO2 emissions and etc…



Why LED Lighting produces lesser CO2 emissions compare to traditional Lighting?

A large percentage of energy comes from the burning of fossil fuels. This in turn releases greenhouse gases into the atmosphere. Less energy needed to facilitate the use of lights means a decrease in the amount of fossil fuels being burnt. Using LED lights will contribute greatly in reducing your carbon footprint.



How long do LEDs for general lighting really last?

LED lights are typically rated to last about 50,000 hours (till burn out). An in-candescent light bulb is rated for about 1000 hours. CFLs or Fluorescent Tube lights are rated for 6000-9000 hours.


What are the advantages of using LEDs over traditional incandescent lighting?

There are quite a few advantages to using LEDs. Generally they are heatless, use 90% less energy, and last ten years. They are also smaller and do not contain any dangerous chemicals like mercury. They can readily be put in places that have always been too small or out-of-the-way for many incandescent lights, as well as in places that were always very dangerous or difficult to get at. Also, the more sophisticated LED apparatuses like wall washers and spotlights are controllable, instant on and off, which means they can be used in some really impressive ways.

The bottom line is that LED's are easier and safer to use than all previous lighting technologies. Plus, LEDs will save you money by consuming less power, lasting much longer, and generating much less heat, which in turn combine to result in lower climate control costs.



Who is using LED lighting?

EVERYONE! Architects and lighting designers are specifying entire lighting packages in their new designs. Contractors are using them in everything from custom kitchens to retail stores. Many homeowners are replacing their incandescents with LED bulbs. LED lighting can replace every instance of old lighting technology, as well create entirely new lighting applications due to its versatility. Your imagination is its only limitation.


Why are some LED lighting products selling very cheap price?

LED lighting products are very similar to consumer electronic and quality really matters. In order for an LED to function properly and provide an acceptable light output, all of the components must be built to last. LED Lighting products consist LED chip, heat and power managements, lens, cables, housing, reflector and etc…With tForce lighting technology, the only quantify components would be used. tForce Lighting product is built to last and delivered bright and good outperformaed with good lighting quality. The value of a lighting product is more than the energy you save. Among other things, it’s the quality of the lighting that you get as an end-result. tForce Lighting only sources LEDs products from Quality Assured suppliers.


What's the quality of LED light?

If you buy quality product, the light quality is excellent. Color Rendering Index (CRI) is generally used to measure light quality on a scale from 1-100. Most LEDs have a CRI rating of at least 70, and many are rated 85 and above.


Can LEDs be used with dimmers?

Some LEDs are specifically listed as being dimmable, but some are not. If you want to dim the LEDs, please select dimmable LEDs. Also, some dimming systems work with LEDs better than others, so it's best to test one or two before completely re-lamping a space.


Are E26 and E27 Light bulb bases interchangeable?

Yes. The E26 is the standard 120 Volt American base. The E27 is the European variant and is rated at 220 Volts. E26 is 26 mm and the E27 is 27 mm diameter. However, an E26 bulb can fit in E27 base and an E27 bulb can fit in E26 base, without problem. The sockets / bulbs are interchangeable except for the voltage rating. Therefore, LED E26 bulbs that are universal line-voltage can be used in both E26 and E27 sockets.



What is the difference Between Lux and Lumen?

Lumen and Lux are two photometric units in the SI system of units. They are closely related to each other and, in simple language, measure how bright a light source appears in two different contexts. These measurements are important in light sources and other cases where the intensity of the light plays a role.


How can comparing Lights Using Candela and Lumens?

Candela and lumens measure different qualities of a light--they are not interchangeable. If you want a light to illuminate a large area, or are concerned with electricity or energy efficiency, then look at the lumen rating. If you want a spotlight or any other lamp that requires a focused beam, then look at the candela rating.



What is lumen?

The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the power of light perceived by the human eye. Luminous flux differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. The lumen is defined in relation to the candela by 1 lm = 1 cd·sr



What is Lux?

Lux is lumen per square meter.
According to Wikipedia, "The difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. 1000 lumens, concentrated into an area of one square meter, lights up that square meter with an illuminance of 1000 lux. The same 1000 lumens, spread out over ten square meters, produces a dimmer illuminance of only 100 lux." 


What is CRI?

CRI (Colour rendering index) measure of how a lighting source renders colours of objects, compared to a perfect reference light source. CRI is given as a number from 0 to 100, with 100 being equivalent to the reference source. tForce LED Lighting always provide good CRI and high CRI  in residential and commercial applications



What types of LED Lighting products are readily available?

Today there are hundreds of different products available in varying brightness levels, color temperatures, and sophistication levels to meet every lighting need – from those of an architect's latest high-rise condo project, to those of a rural homeowner's kitchen renovation. There are replacement bulbs for screw-in Edison-style bulbs and for nearly every style of Fluorescent. Plus, the LED replacements are of the “plug and play” ilk with no other modifications needed. There are also many different types of architectural lighting, such as wall washers and led spotlight.

Finally, our most popular piece of LED lighting is the light bar, which can be used anywhere. From display cases to under-cabinet lighting, our light bars offer a novel (and cost-effective!) approach to accent lighting. The most exciting product that we are currently working with is a 9 watt recessed light that many contractors are replacing all their incandescent can lights with.



How do I compare my current lighting with LED lighting so I can make intelli-gent decisions?

In the past, we have generally referred to the brightness of a bulb in terms of its wattage, or the amount of power that the bulb uses (or energy it consumes). Because of the disparity between incandescent and LED technologies, we have to change our language a bit in order to account for progress. When referring to brightness, we now find ourselves comparing lumens (see Q: What is a lumen?). However, when comparing LEDs with incandescents, there is no easy mode of comparison because the typical incandescent is projecting light in 360 degrees – everywhere, not just where you need it. Because LED lights are directional, they focus all the light they generate exactly where you want it, and nowhere that you don't.

Another consideration is color temperature. In the past, this has been very difficult to control because you basically got whatever color your particular bulb produced. Typically this was a Warm White (about 3000K) if you had an incandescent bulb, and a Cool White (around 5000K) if you had a fluorescent bulb. Because the LED is an intelligent, solid-state technology, we are able to produce LEDs that not only produce Warm White and Cool White, but are able to produce up to 16 million different colors, each a different temperature.



How can I replace the traditional fluorescent tube for LED tube?

We recommend when replacing a traditional fluorescent lamp for a LED T8 lamp, the existing control gear should be disconnected and rewiring of the internal circuit maybe reqired. This should only be carried out by a qualified electrical engineer.


Should LEDs be used in enclosed fixtures?

Not if they are completely enclosed. In order for an LED to function correctly, they must be in a non-enclosed fixture to allow for heat to dissipate from the heat sink. Otherwise, they can overheat and may fail early. Please consult any local quantify electrician before you do so.
