Photometric Lighting Analysis
Does ILD offer a free photometric analysis to every caller?We offer photometric analysis for a marginal fee to clientele seeking just a report, and complimentary analysis to clients who hire us for lighting design. Lighting is an art form that requires careful consideration from a seasoned lighting professional.
What software do you use to generate photometric reports?
We use AGI32, a lighting design, a 3-D modeling suite that calculates light levels and renders electrical lighting systems. The capabilities of this photometric analysis software are amazing. By generating 3-D model of the room, home, or building, the software allows us to input hypothetical figures to determine where best to install recessed lighting fixtures and what angles of lighting incidence to incorporate in the overall design of the system. It can be used to determine the best possible lighting levels for any residential or commercial lighting environment.
Why should I have a photometric analysis done rather than just hiring a freelance contractor to install lighting fixtures I buy myself?
The human eye cannot always see every potential problem area of darkness and shadow. Every outdoor or indoor environment contains physical objects that will cast shadows when light strikes them from certain angles. Shadows are cast not so much by inadequate amounts of light, but rather by inaccurately calculated angles of incidence that send a beam of light straight toward a solid object which blocks luminance completely on the other side. Many times, these areas are very hard to find from an eye-level perspective, but later become all too evident once low voltage recessed lighting fixtures have been installed and shadows suddenly spring from out of nowhere.
The 3-D modeling aspect of our photometric analysis software allows us to literally move around these objects from any angle, height, or perspective to see where best to locate a ceiling light, lamp, recessed fixture, recessed art lighting, pendant, or chandelier. We can also try different wattage and bulb hypotheticals to determine the most efficient lumens per watt ratio once the optimal angles have been located. In commercial environments, this goes a long way toward saving businesses a great deal of money.
What aesthetic benefits does a photometric analysis offer my company?
We can conduct a room by room photometric analysis of floor space and vertical cube space to determine precisely where to install lighting equipment and exactly how much power each light will need to do its job. This is very similar to the way interior design partners and space planners work—creating individual sub designs within the overall design of the facility. This enables our team to develop a much more energy efficient, Spartan system that relies much more on design, light distribution, and precise lighting angles than it does on excessive numbers of fixtures using more power than necessary. Another benefit you gain from a photometric analysis offers is better fixture concealment. Because the report tells us exactly how many watts and lumens we need for each fixture, it is often possible to use smaller, more concealable lights for a more aesthetic compliment to the overall environment.
What lighting manufacturers do you represent?
Essentially, we act as a design build contractor for all of the major manufacturers headquartered and operating here in the United States such as Lutron Radio Ra dimmer controls. Choosing the right manufacturer for your needs is again accomplished in part through tools available in AGI32’s photometric analysis software. AGI32 actually contains manufacturer’s spec sheets and engineering documents on specific fixtures in different categories. We can use this database to generate a luminaire comparison report instantly that details optics, lumens per watt efficiency, and expected lamp life. By comparing and contrasting necessary and fixture placement recommendations with specific data on each luminaire, we can pinpoint the best possible quality and energy efficient luminaires to use in commercial, residential, and high-end lighting design.
