Technical Specialisms

SILL Lighting has a reputation for being highly specialised. Below is an alphabetical list of SILL Lighting technical specialisms. This list is not finite. Should you require further information on any of these or others not included then please contact us direct.
At SILL Lighting, we believe in putting light where we say we will – and nowhere else. As an integral part of SILL Lighting’s approach to the close control of light we produce a wide variety of accessories for use in conjunction with our luminaires. These vary from adjustable screen / barn doors with additional lockable opening blades to block any light spill through the corners, to gimbal mounting options for use on board search and rescue lifeboats; and everything in between.
This can be a very tricky and complicated exercise and requires certain expertise to hit the ‘aiming points’. An example would be the floodlighting of a stadium for TV coverage: in order to meet the stringent requirements of lighting levels, glare and uniformity; and in order to mimic the lighting design accurately. SILL has a long history of providing this service for High Power Sports Floodlighting
SILL Lighting has a wide range of technical luminaires, with precision optics, and specialised accessories. This is primarily to do with putting the right amount of light where it is intended and nowhere else.

Many of our clients have concerns that our products once specified, might not then be installed correctly, or not provide light quite as intended and, for instance, might not be aimed as well as they might.

SILL Lighting offer a commissioning verification service to help overcome these potential shortfalls. We will attend site and carry out suitable and relevant inspections and checks, and where necessary help to e.g. aim the luminaires, adjust any cowls and shields, provide advice on maintenance procedures etc.
CLO is software included within the power supply to regulate the power to the LEDs to compensate for their loss of output over time. As such it can also be utilised to avoid excess lighting at the beginning of the installation's service life. CLO is available as standard on some SILL products and as a variant on others.
We carry a wide range of standard brackets, clamps and different mounting options. However, many installations require something unusual and different e.g. pivoting multi-head; extended brackets; additional safety wires; vibration damping; gimbal mounting; ground spikes and so on. In these instances, SILL Lighting will help design, and supply a solution to suit.

WEEE and RoHS: SILL Lighting fully complies with the Waste Electrical and Electronic Equipment (WEEE) Directive and The Restriction of the use of certain Hazardous Substances (RoHS) Directive. Customers may find their selected contractor will dispose of any electrical waste in an appropriate manner. Alternatively, should you wish us to collect any waste luminaires in order to arrange the disposal our ElektroG (WEEE) Waste Compliance Officer should be contacted. Please note that we reserve the right to charge for this service as we do not charge at the time of purchase.
SILL Lighting do not manufacture Emergency technology: instead we will implement the right solution as best suits the installation: Please see under Custom Product.
SILL Lighting will always strive to offer the most energy efficient solution for the application. This can be achieved by utilising LED in many installations. Please bear in mind that on occasion though, (typically larger wattage) metal halide lamps are (still) more efficient than LED! Less well publicised is the more efficient use of mounting positions i.e. less luminaires; better designed optics and better lenses producing more efficient photometry and putting the light where it is intended and nowhere else, etc. Our in-house factory electricity is sourced from a 100% renewable source. The quality of the materials ensures maximum recyclability.
The majority of exterior lighting installations will have some requirement to reduce glare and / or nullify it completely. By a combination of computer driven lens design, world renowned reflector design, optics design, and selected filter technology SILL can take the designer and installation a long way down the road to negating the ill effect of glare altogether. SILL has a patent pending on certain lens / photometry combinations.
The body shell of SILL luminaires is made of high quality aluminium alloy; the actual grade is known as EN AC-Al Si12. The difference is the ≤0.1% copper impurities; the advantage is the improved corrosion resistance and thus the ultra-long life in even the most demanding environments. Stainless steel (A4 is offered as a standard option) fixings are according to DIN17440. Front cover glasses are toughened and sealed by UV resistant silicon gaskets. Internal wiring is high temperature resistant silicon or PTFE (polytetrafluoroethylene).

  1. For areas where there is proximity to marine, and / or a saline rich atmosphere: please ask for our SEELACK additional anti-corrosion protection. Typical installations would be those near to coastal areas and swimming pools (chlorine).
  2. ‘Hard anodising’ is available for those products requiring additional protection against wear and corrosion: for particularly harsh environments. An example would be a more extreme coastal installation with constant high wind speeds. Please contact us for more information.

LED solutions usually offer an energy efficient way of providing a similar amount of light over more traditional light sources. This in turn means the end user (or whoever pays the electricity bill!) can experience a finite pay-back period: the upfront cost will eventually be nullified by the swop to a more efficient technology. However, the upfront cost might scare off some users who might otherwise hesitate to make the initial capital investment in LED. SILL Lighting offers a Leasing Option whereby the capital cost of the equipment is paid back over a number of months and / or years; with ownership being handed over with the final payment.
Lighting is no longer just luminaires. Nowadays lighting is the combination of the luminaires in conjunction with the lighting control. Lighting technology is moving forward at a rapid pace. As such SILL luminaires will typically work with all control protocols e.g. DALI, DMX, etc. and as SMART Cities and LIFI look to become the norm, we are striving to be at the forefront of offering solutions with these technologies too.

CMS antennae, PECU (Photo Electric Control Units) with 2 way controls, failure reporting, daylight linked dimming etc. are all standard options.
Light Trespass is now a statutory nuisance in the UK. Light Pollution has long been considered Environmentally unsound. In the vanguard of this is Astronomy. The quality of the sky astronomical research and observation over the Canary Islands is so exceptional that it has even been protected by a law, known as the ‘Sky Law’. The renowned Instituto de Astrofisica de Canaria (IAC) has commended SILL Luminaires for their sky-protecting light quality.
SILL Lighting have world class optic and reflector technology, available across a uniquely wide range, displaying high precision and efficiency. We have our own in-house independently tested photometric laboratory with photometer. See also Accessories.
With the current mass exodus to LEDs away from more traditional light sources (e.g. metal halide) it is important to consider all the aspects before committing to expenditure. Typically, LED luminaires cost more than their metal halide alternatives: and typically LED luminaires are more efficient than the metal halide alternatives. But this is not always the case: LEDs are not always the most efficient light source. SILL Lighting will provide you with an accurate prediction of the likely payback period of selecting certain solutions for your application. Please contact us direct for your calculation.
There is a burgeoning debate as to how LED light might affect plant growth. Photosynthesis does not require UV. However, whilst photosynthesis utilises sunlight, if that is not available then more of certain specific ranges of the spectrum would appear to be more important in the process. (The current lighting research science appears to favour the blue, red and IR parts of the spectrum as the most important for (green) plant growth, weight colour, flavour etc.). SILL offers the option of including variant LEDs within the same light fitting. As well a number of additional lens options.
Such is the longevity of SILL Lighting luminaires that we carry the relevant spares for many years, far beyond any legal requirement. Long after any other manufacturer’s products have been replaced SILL products are still operating. Occasionally due to vandalism or the extreme wear and tear of a component, we are asked for spares. Rarely do we disappoint. Even if we do not list the spare in the catalogue / website please approach us direct for help.
SILL Lighting offers a ‘one stop’ solution for those clients who wish to have us supply and install our light fittings.
The case against the use of cool white / blue-rich (LED) light has growing support in many quarters; especially with regard to discomfort glare, circadian rhythm disruption, light scattering, sky glow and in particular the biological system disruption in wildlife. In natural settings, at night it has been shown adversely to affect certain wildlife behaviour and reproduction. A well-documented example of this is in areas where turtles’ eggs hatch: it is important that the newly hatched turtles head for the glow of the ocean horizon and not the artificial lights in the other / wrong direction. Research is also ongoing into the use of LED lighting with bat welfare: early results would indicate that LED based cool white / blue-rich LED light might be interfering with the bat feeding patterns. One way to mitigate against these issues is to use Amber coloured LEDs which are standard to the SILL range.
