UPS and inverter backup units can be classified into two main categories, true sine wave and “quasi” or “simulated” sine output and are usually specified by their VA and Watt rating. Oscillogram 1 shows the voltage (red) and load current (yellow) of typical 600VA “quasi-sine” UPS with 10x Verbatim 8.5W GU10 LED’s (#52310) without a [...]

The Real Benefit of dimming LED’s

LED lighting is a new technology that gained market acceptance in a very short period of time,  probably only paralleled by the mobile computing industry.  Initial teething problems can thus be expected with such rapidly evolving technology. However, unlike the tablet and smartphone industry where a simple software update usually addresses most of the problems, [...]

EMI (electro-magnetic interference) – a legal and insurance requirement

By |2017-07-11T14:01:47+01:00June 3rd, 2015|Categories: Editorial|

It is rather ironic that in a modern world where we are concerned about greenhouse gases, smoking, genetically modified foods and nutrition, the consumer often spends good money unwittingly exposing themselves to possible sources of high EMI. This is especially in the case of modern solid-state lighting such as LED lamps and even more so [...]

Can dimmers and electronic lamps (such as LED’s and CFL’s) damage each other?

By |2017-07-11T17:20:35+01:00June 3rd, 2015|Categories: Editorial|

Any electronic device can fail.  If a stand-alone product is designed correctly, failures are mostly due to operating it outside of specifications, mains related induced failures such as lightning strikes, a grey component failing, end of life failures, etc. and it's normally fairly easy to establish the cause of the failure.  However, in the case [...]
