Anti-glare
What Are UGR Ratings?
Our extensive experience in energy-saving lighting projects highlights the importance of anti-glare lighting in settings like hospitality, healthcare, education, and offices. Anti-glare products enhance visual comfort, safety, and efficiency by providing low Unified Glare Ratings (UGR), which reduce discomfort, control light spillage, and optimize light distribution.
UGR measures the risk of glare, with values ranging from 5 (very low glare) to 40 (extremely high glare). For educational and office environments, a UGR of 16-19 is ideal.
Choosing appropriate UGR levels is crucial for creating comfortable, visually pleasing spaces that enhance concentration, productivity, and overall performance.
Reduce Discomfort
High levels of glare can cause eye strain as our eyes have to continuously adjust to varying brightness levels. By using lighting with low levels of UGR, our eyes are strained less and thus discomfort is reduced.
Control Light Spillage
Fittings are employed to ensure that there is precision in the direction of light and beam angles are used to ensure that light is confined to the intended areas. These methods minimise spillage.
Optimise Light Distribution
Low UGR products allow for precise lighting control which enables light distribution to be more controlled and efficient.
What are The Key Ways to Reduce Glare?
Position of light fittings
We will assess the position of room occupants in relation to the placement of light fittings. It is good to attempt to position lights so that they aren’t in the direct line of the occupants sight.
Height of suspended fittings
We will consider the choice of height when installing suspended light fittings. It could be prudent to suspend light fittings at a lower height in order to reduce glare.
Narrower Beam Angles
We can supply lighting with narrow beam angles. It is possible to reduce the perception of luminous intensity by choosing ceiling mounted fittings with narrower beam angles.
Recessed Fittings
We can advise on fittings where the LED or light surface is recessed which means that the direct and reflected glare is reduced.
Uplighter Fittings
We can provide uplight lighting which projects light onto the ceiling. This will decrease the contrast of the lighting between the background and the fittings themselves, thereby reducing the UGR.
At Lightsave, our projects team help clients consider the UGR in the different areas of their site and suggest the appropriate products as a resolution.
