Diffuser / Fixture Compatibility
The compatibility of the diffuser and light fixture is very important. Price has worked with most light fixture manufacturers to ensure the compatibility of the two components. Most problems occur when special light fixtures are used in both flush slot and regressed slot types. To ensure the compatibility of standard or special flush slot or regressed slot light fixtures with the LT diffusers, the preferred procedure is for the light fixture manufacturer to provide an approved, fully dimensioned drawing. This will enable Price to check the fixture connstruction and slot configuration. This procedure should be followed up with the supply of a production sample fixture to allow for a check on the physical diffuser and fixture compatibility and the performance of the diffuser on the fixture. |

Regressed Slot Fixture
This applies to fixtures which have a continuous reveal around the fixture lens. The configuration of this reveal varies a great deal depending on the fixture manufacturer. The depth and width of the reveal varies and may contain a commbination of air deflector and blank-off. These items can have a significant effect on the performance of the LT diffuser with regard to pressure drop, noise level and air pattern. For this reason, it is important that compatibility and perrformmance be verified on regressed slot fixtures.
Surface Slot Fixture
This applies to fixtures where the supply air slot on the fixture is essentially flush with the ceiling surface. The performance data in this catalog applies to all surface slot fixtures. |
