GU10 LED Bulb incredibly dangerous product

Posted on Updated on

This GU10 LED spotlight is marketed as giving a lot of light at low cost, but the adverts don’t mention that it’s an incredibly dangerous product! When you hold the metal casing to insert the light, there’s a 50% chance that live mains will be within a few microns of the casing. Since there’s no earth, you have no protection from that charge.

Basically, using this product is equivalent to playing Russian roulette with 240v AC mains. LED products are safer on balance, but products like this give the technology a bad name. Steer clear, the money saved isn’t worth the risk of harming yourself, your employees or your family.

Given the risks associated with shoddy LED products, it’s essential to purchase safe, high-quality products rather than buying from cheap providers who skimp on safety. TForce LED enforces tough safety standards so we can guarantee that our products are high-quality and 100% safe.

Comparisons Between LED Tubes And Fluorescent Tubes

Posted on Updated on

The Purpose Of Using LED Lights

Nowadays, more and more people are talking about the hot topics of energy saving, on the purpose of protecting our planet which is being dried up. At the same time, people are aiming to save as much as money that is rolling out from their pockets under the current economics situation.

Among those subjects, LED lighting is no doubt to be one of the efficient ways to conserve energy and money. There have been many different types of led lighting fixtures available on the current market to replace the traditional “old-style” lighting fixtures. Most of the led lights are designed to have the same interface as that of the traditional lighting fixtures, on the purpose of fitting the led lights into the existing fixtures.

The Design Of LED Tubes

However, in fact, this is really not rational and scientific designs. In order to cater to the existing fixtures, the designs of LED lamps have been greatly hampered. For example, most of the LED globe light bulbs are still having old lamp base like E27 or B22 etc. However, such lamp bases are actually not good options for the led light bulbs when considering the heat dissipation issues which is crucial in the design of led lighting fixtures. In a E27 or B22 style LED bulb, the LED driver is being placed in a very limited space, which is not good for heat dissipation at all. However, such kind of designs are involuntary as the primary issue is the consumers. Only the consumers are willing to use, LED lights can move forward. As a result, easy installation has to be considered during the development of the led lighting fixtures. Therefore, this is considered to be some kind of compromise.

LED tubes would be a product of one of such compromises. LED T8 tubes follow the traditional T8 fluorescent tubes, using G13 standard interface and pins. So that the led tubes can be used to replace the conventional fluorescent tubes very easiy.

In addition to the exact same interface, the length of the LED tubes have to be consistent with the old-styled fluorescent tubes. Thus, the typical length of the led tubes you can see would be 600mm (2ft), 900mm (3ft), 1200mm (4ft), 1500mm (5ft), 2400mm (8ft). In most of the countries and areas, 600mm (2ft) and 1200mm (4ft) tubes are commonly seen. But in some countries, 1.5m (5ft) tubes can be seen more often, for instance, in the UK. In Japan, many factories or commercial buildings are using 2.4m (8ft) tubes for lighting. LED tubes follow the rules too.

The Efficiency

There are some advantages of using led tubes to replace fluorescent tubes, among the key points, energy saving is of course a crucial one. With high efficiency, LED tubes can consume about 40% of electricity to provide equivalent light output to a fluorescent tube. The typical replacements would be: 8-10W LED tube to replace 20W fluorescent tube; 16-18W LED tube to replace 40W fluorescent tube; 24-26W LED tube to replace 60W LED tube, and etc. And as a matter of fact, in pratice, the LED tubes have better performances than the conventional fluorescent tubes. And as the LED technologies developing, the advantage of LEDs will be bigger and bigger. efficiency will be higher and higher. One should not be surprised if one day, you are told that a 40W fluorescent tube can be replaced by a 4W LED tube. But of course, when that day comes, the fluorescent tubes had long been wiped out and become a exhibit in the museum.

The Working Lifespan

The working lifespan of a traditional fluorescent tube is around 5,000 hours. In pratice, one fluorescent tube needs to be replaced not longer than one year if the tube is working for long hours every day. Plus, frequent switching can easily damage a fluorescent tube. While, it is not difficult for a decently designed LED tube to be working longer than 30,000 hours, and even longer. And, frequent switching is not an issue to LED tubes.

The Light Quality

The light source types of fluorescent tubes and LED tubes are different, one is multi-directional light source, and the other is directional light source. As a result, all directions around a fluorescent tube are lighting up in the same degree when a fluorescent tube is turned on; while, led tubes are more concentrated, you will find the front of a led tube is the brightest, and the back of it is much be darker. This is also the reason why LEDs are more efficient, as much light as the fluoresent lamps do.

The colour temperature of a traditional fluorescent tube is typically 6500K, that is called cold white. While for LED tubes, the colour temperature usually could be from 2500 to 7000K. The most commonly seen light colour temp is 2800 to 3300K which is known as “warm white”, 4000-5000K which is known as “neutral white” and 5500-6500K which is known as “cold white” (or “cool white”).

The typical CRI (Color Rendering Index, “a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source” – definition by Wikipedia.) of conventional fluorescent tubes is around 65. While, LED’s CRI can be from 70 to 85 and even higher. Higher CRI enables LED tubes to have better performance of reproducing the colour of the objects.
