Cleanroom Lighting

Fluorescent and LED Lights
  • Make it easy to configure the optimal lighting for your application
  • Select 2' x 4' (610 mm x 1219 mm) ceiling module for placement in the ceiling grid, or Teardrop Lights for installation below the grid
  • Flow-Through units are ideal with dense FFU ceiling coverage
  • LED light strips produce less heat and are more energy-efficient

Terra offers four lighting modules.

For applications that do not require 100% FFU ceiling coverage, 2' x 4' (610 mm x 1219 mm) illuminators can be positioned in unused ceiling grids.

For applications that require total or near-total FFU ceiling coverage, teardrop and flow-through lighting modules are available. Teardrop fluorescent lights mount to the ceiling grid in-between the FFUs. Their aerodynamic design does not interfere with the laminar airflow. Each of these single-tube lights requires 6" (152 mm) of vertical clearance below the FFU filter face.
 
As an alternative to teardrop lights, you can select 2' x 4' (610 mm x 1219 mm) flow-through lights, which are stacked below the FFU. Flow-through lights add 4'-3/4" (121 mm) to the ceiling height but require no vertical clearance below the filter face, making them ideal for low-ceiling cleanrooms.

If energy-use or bulb replacement frequencies are concerns, choose double-stacked light-emitting diode (LED) light strips. The lumen output is similar to fluorescent, but the bulbs can last 5-8 times longer. You’ll see a dramatic reduction in heat produced, and a savings of greater than 25% of the energy consumption. The strips are mounted on the ceiling T-grid, so there is no obstruction of laminar air flow.


Teardrop light
Teardrop Light

A. Teardrop Lights
Ideal for ISO 3 or higher cleanrooms, in which near-100% filter coverage of the ceiling leaves no space for standard fluorescent light modules. This aerodynamic design ensures minimal interference of the laminar airflow; the T8 lamp provides 3,150 lumens. Housing is made of stainless steel. Dimensions: 48.5"L x 2.5"D x 6"H (1232 mm x 51 mm x 152 mm). Price includes installation (specify desired location when ordering).

D. Flow-Through Module
Low-profile, fluorescent-tube module creates a light source underneath the fan/filter unit without obstructing air flow. Attach this “cage” beneath a 2' x 4' (610 mm x 1219 mm) FFU; adds 4.75" (121 mm) to ceiling height. Intensity: 8560 lumens from the four T8 lamps. Must be ordered together with FFU.

on a cleanroom ceiling grid
E. LED Lighting
Streamlined LED strips are double stacked and attached with hardware to the ceiling grid T-bar. Bulbs produce less heat, require less energy and last up to five times longer than fluorescent bulbs. Sixteen feet of LED bulbs produce 9800 lumens (equivalent to a 2’ x 4’ four-bulb fluorescent fixture). Price includes power supply and installation; specify linear foot at time of cleanroom order (25-foot minimum). Sign-off drawings will specify light lengths and locations
