TESS Unveils a New Dimmable LED Bulb Dimming to 5 Percent

TESS (topco energy saving system corp.), a leading LED lighting developer and manufacturer in Taiwan, newly presents a dimmable LED bulb to market. This dimmable LED bulb can be steady dimmed from 5 percent the lowest brightness level to 100 percent the highest.

This new dimmable LED bulb of TESS utilizes CREE XP-G LEDs, consumes 12 watt of electricity and delivers 810 lumens output which is equal to 80 watt incandescent bulb. Also, the dimmable LED bulb provides warm white light and sustains more than 10,000 hours life time.

The dimming capacity of most similar dimmable LED bulbs found in market is from 20 percent to 100 percent output, yet the TESS dimmable LED bulb can bring the lowest brightness level down to 5 percent output. The secret lies in its unique circuit design.

“Developing technique is absolutely a key to create such a good performance,” said chairman of TESS Sunny Tsai. “It is not a problem for other competitors to obtain similar or the same components like TESS. They can also have our new products and unravel them and still not be able to figure out how to bring the dimming capacity to a new level. Not only developing techniques but also experience you need to push the functions of components beyond limits.”

One more crucial feature that makes TESS dimmable LED bulb stand out among many similar products is its smooth and stable dimming ability while others flickering and even buzzing during dimming. Unlike undimmed CFLs and energy consumed incandescent bulbs, TESS dimmable LED bulb can create cozy and intimate atmosphere at home or apply to any scenario occasions simply do not need so much light. The power consumption decreases as the light dims, though LED bulbs use less energy comparing to CFLs and incandescent bulbs with the same or similar luminaire efficiency.

Besides this dimmable LED bulb, TESS announces 12 watt 1200 lumens LED bulb, 3 steps color-temperature adjustable LED bulb, the world’s first GX10q-4 base LED PL (BB type) lamp and LED T8 tube at the same time.

LED Lights Advantages
Efficiency: LEDs emit more light per watt than incandescent light bulbs. Their efficiency is not affected by shape and size, unlike fluorescent light bulbs or tubes.

Color: LEDs can emit light of an intended color without using any color filters as traditional lighting methods need. This is more efficient and can lower initial costs.

Size: LEDs can be very small (smaller than 2 mm2) and are easily populated onto printed circuit boards.

On/Off time: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in under a microsecond. LEDs used in communications devices can have even faster response times.

Cycling: LEDs are ideal for uses subject to frequent on-off cycling, unlike fluorescent lamps that fail faster when cycled often, or HID lamps that require a long time before restarting.

Dimming: LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current.

Cool light: In contrast to most light sources, LEDs radiate very little heat in the form of IR that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED.

Slow failure: LEDs mostly fail by dimming over time, rather than the abrupt failure of incandescent bulbs.

Lifetime: LEDs can have a relatively long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000–2,000 hours.

Shock resistance: LEDs, being solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile.

Focus: The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner.
