How to select the right lamp for the right purpose
Author: GE LED
Soft or more aggressive? these two words are often contradictory, but that doesn't have to be always true when we talking about lighting design.
Reduce the glare at the same time of adding more lights, an increase in brightness can also be done in a soft way.- only if you know how.
These are what we are taling about:
The amount of lumen output seems just right for lighting up a working platform, but the effects can be different from "just right" to "OMG this is gonna give me a headache".
That is because of the beam angle for the downlight on the left is 80° and it is not designed to hide the light source in a narrower beam angle as the sport light on the right does.
So when we come to a choice, if it is for general lighting purpose, then choose wide beam angle downlights with a matt diffuser would definitely save cost, but if it is for certain tasks
then a good Anti-glare recessed portlight/downlight is needed.
They usually come with a recessed trim that could expend the shielding angle to 45°-60° .
There is an easy way to identify the shading angle of the human eye: If you look at the product picture or feel it in kind, the depth “d” ( the light from the lamp plane to the light source ”and the length of your thumb are similar, then the shielding is about 45 degrees. This kind of lamp has less glare
37° Beam Angle’s effect
60° Beam Angle’s effect
The complexity of the Reflector & Lens’ design determines the quality for the light beam it casts out.
