When people think of LEDs they think cumbersome design, large chips, silver collars and a high lumen output. Up until now, they would by and large be correct. LEDs are undoubtedly highly functional. However, in many cases they are badly designed with questionable light quality.
Tala adopts a classic design aesthetic alongside high-performance components in order to create an elegant LED bulb. By mounting high-performance chips onto columns of sapphire substrate, the design remains minimalist whilst ensuring excellent performance capabilities.
The design marries the best of the Edison light bulb features (instant, warm, flicker-free, filament style) with contemporary energy performance. Our customers want the traditional look of the filament bulb at the same time as receiving all of the technical and energy saving benefits of LED.
All Tala products are designed in the U.K. and manufactured in China. Our in-house team of electrical engineers and designers oversee everything from the driver technology through to the glass moulds of our products. In the interests of transparency, we welcome all Tala clients to come and visit our dedicated R&D lab at our studio in London to experience our work first hand.
Similarly to the traditional bulb, we have kept the blown glass envelope to promote even and omni-directional light. The clean design uses geometrically arranged cylindrical LED filaments to mimic the aesthetic of the Edison. The result of this is a clean, warm and simple bulb that can be used in every environment. Other filament style LEDs come with a bulky collar to hide the driver (the part that regulates how much electricity enters the LED from the power source). Tala bulbs use much smaller drivers, crafted with a variety of heat dissipation technologies, making the collar obsolete. The result of this is a bulb that’s comfortable in any design situation.
LEDs have several advantages:
· High efficacy (90% more efficient than incandescent lighting)
· Durability (we source parts of the highest quality)
· Minimum life span of 15,000 – 30,000 light hours
· Reduced lighting maintenance requirements
· Return on investment in under 1 year
These factors translate into considerable energy savings, maintenance savings and environmental sustainability. There is also the potential for greater optical control (more controllable source), dimming, instant on/off, and reduced rate of lumen depreciation (potential for long application life).
There are two important factors to consider when talking about energy saving – the environmental impact of lowering your energy consumption and the financial impact of using less electricity. By switching to LED, you are reducing both your energy bills and your Carbon Dioxide output.
Tala 6W Gaia is equivalent to a 40W incandescent bulb.
Original bulb wattage: 40W
Replacement wattage: 6W
Watts Saved: 34W = 0.034KWh per hour
Hours of use per day = 4 hours
Days of use per week = 7 days
Weeks of use per year = 52 weeks
Total kWh saved per year (0.034 x 4 x 7 x 52) = 50 kWh/year
Energy cost per kWh (UK average) = £0.15
Potential cost savings per Tala 6W bulb per year: £7.5
You will also save the money spent on replacing failed incandescent bulbs.
On average an incandescent lasts 1,250 hours, needing replacing once a year.
A 40W Edison G125 incandescent bulb costs on average £5
Saving per Tala 6W bulb per year: £5 + £7.5 = £12.5
Saving per bulb over lifetime of Tala bulb = 20 x £12.5 = £256
Payback on initial spend = 2.8 years
* This case study does not factor in rising energy prices which additionally would reduce payback time and the cost of your energy bill.
We have a range of outputs to suit different scenarios, from 100lm to 540lm.
Based on how long a fixture is illuminated per day, here is what 30,000 hours works out to be:
· 24 hours per day: 3.5 years
· 18 hours per day: 4.6 years
· 12 hours per day: 7 years
· 8 hours per day: 10.27 years
Our filaments are externally tested using LM-80 and TM-21 standards to provide lifetime calculations.
– For our sapphire filaments (rigid, straight filaments) we recommend 30,000 hours. External testing shows it is possible to recommend 33,000 hours. These calculations are relevant to all products in the Tala portfolio except Voronoi, Basalt and Unum.
– For our FPC flexible filaments – external testing recommends a value of 15,000 hours useful lifetime. ‘Useful’ is defined as still emitting more than 70% of the original light output. This applies to the Voronoi range only.
No. Unlike incandescent and fluorescent light sources, Tala LED lighting products produce virtually no light in the Ultraviolet (UV) or Infrared (IR) spectrums.
Colour Rendering Index (CRI) is defined as a light source’s ability to render colour. Essentially, the measure is intended to characterise the quality of light emitted by any given bulb. CRI is rated from 1-100. The higher the CRI, the more accurately the light source renders every colour in the visible spectrum. To have what is generally considered good colour rendering, a source must be greater than 80 CRI. Tala LEDs all have a CRI count higher than 95, making them perfect for gallery-quality lighting.
Power factor is the term applied to the efficiency with which the supplied power is used within an installation. A high power factor means that the electrical power is being used effectively, while a low power factor indicates poor utilisation of electrical power. Power factor is a measure of the real producing current in a circuit relative to the total current in that circuit. It indicates how much real work is being done relative to the total amount of current drawn by an electrical device. Tala bulbs have a power factor of up to 0.97, placing them at the top end of the market.
We offer E27 (E26 US) & E14 (E12 US) bulb caps
For regions including the UK, Europe and Asia.
We aim to test the most widely used dimmers on the market to guarantee the best possible performance with our LED bulbs and Light Engines. The phase-control dimmers below have been tested in our London lab and proven themselves to deliver smooth, responsive and stable dimming from full power down to zero or near-zero light output. For best results, ensure your electricity supply is stable and free from transients.
