Indirector Series

The Indirector by design is intended to light ceiling and wall surfaces. The variety of lamp sources available to the Indirector fixture offers many options for both indoor & outdoor illumination. Each lamp source has particular characteristics that must be considered when doing each design application. The application information below is intended to provide you with general guidelines when considering the Indirector luminaire for your project.

	Fixture Orientation Proper placement of these fixtures is important in order to maximize the uniformity on the target surfaces, as well as minimize the potential of glare. It is important to combine the information regarding setback, aiming and spacing, with the individual photometric information provided for each fixture in order to obtain the desired results.

Fixture Setback The setback is the distance from the fixture to the target surface, measured perpendicularly. In order to avoid excessive bright spots on the wall/ceiling, the proper setback distance must be determined. Along with avoiding the hot spots, the throw distance on the target surface must be considered to provide proper illumination along that surface. As you go up in lamp wattage / lumen output your setback too will increase in order to maintain your uniformity. In general your setback should be about ¼ the length of your target surface. That distance should never be less than 30” even in the lowest wattage fixtures. Refer to the individual photometric pages for each fixture type for more detailed information.

	Fixture Aiming The proper aiming angle for the Indirector fixture will need to be determined using the maximum candlepower & the overall throw distance for the surface to be illuminated. In order to obtain the maximum uniformity the aiming point of the maximum candlepower should be at a distance of 3/4 to 7/8 that of the overall throw distance. The angle or maximum candlepower can be found on the individual photometric pages of each fixture type. All Indirector fixtures offer multiple means of fine tuning your installation.


• The fixture arms, at the back box have the capability of adjusting vertically (up and down) as shown in the literature. This not only will give you aesthetic options but can help you create different fixture head aiming angles. This adjustment has 7 locking positions to insure all fixtures will be identical in positioning. • The fixture head is capable of rotating within each setting. This angle allows you to maximize the aiming angle for any design project. Combine this with the adjustable back box arm and your variations are virtually limitless. • Use the Indirector markings on the cast arms and fixture head end plates to assure identical positioning among fixture groupings. The fixture includes a bubble level to adjust fixture heads to the most common aiming angles. (See chart at right for common fixture angles by housing size and distribution.) Full range of motion may be restricted on some wattages due to thermal restrictions of mounting surface. Refer to bulletin in packaging for details. • The internal reflector has the capability of being aimed 10° below the horizontal plane. These reflectors will be set at the factory but will offer some additional fine tuning so the end user can make internal adjustments while maintaining the head orientation. (Halogen fixtures do not have this adjustability).


Spacing Spacing is the on-center distance that the fixtures are mounted apart. The spacing should be dependent on the setback and should fit in with the aesthetics of the space as well. Proper spacing is vital in order to maintain a lateral uniformity on the target surface. It is recommended not to exceed a spacing of 2 times the setback distance to maintain the optimum uniformity. Refer to the individual photometrics pages for some sample spacing charts.

Glare, Brightness & Fine Tuning Despite the best of design efforts you may still run into a situation where glare or fixture brightness can be an issue. Combined with the multiple fine tuning adjustments built into the fixture, the Indirector fixture has some options & accessories which should be able to assist you in any situation. • When uplighting, it is important to locate the fixtures above the eye level. As the fixtures are mounted nearer that level and aimed out towards the target surface, the opportunity for glare is increased. In these cases a visor may be called for to raise that angle of incidence. • When washing down a wall it is important to locate fixtures to avoid aiming at doorways and seating areas adjacent to the walls. In order to cut back on the glare and have better control of the light distribution a visor or barn doors may give you the added control you need.
