Part Numbering Explanation for this model:

         

Part number: PRL-97704-2C-G-PLB-MT-M20

 

 

     
The PRL LED (specify: color), (specify: voltage) 50/60 Hz semiflush light shall operate properly within an input voltage supply range of 93V to 144V for 120V units and for 176V to 250V for 220V units. Within the preceding ranges, the output to the LED board shall be a controlled, stabilized constant current. The light shall be affixed to the metal helideck with six (6) stainless steel screws (by others) evenly spaced centered on a 10-¼ inch bolt circle.
          

The heliport lights shall be listed Suitable for Use in Wet Locations to UL 1598A Marine Vessels (for AC), UL 1598 2nd Edition Luminaries; CSA C22.2 No. 250.0-08, 2nd Edition; UL50 11th Edition Standard for Enclosures for Electrical Equipment and CSA C22.2 No. 94-M91 Special purpose Enclosures for use at -40 deg C to +55 deg C and sealed to IP66 and IP67 ingress protection.

  
The light shall be compliant and tested to UK CAA CAP 437 ed. 8, Chapter 4 and Appendix C including IP66 & IP67.

  
The light shall be cast aluminum and assembled with all external hardware grade 316 (A4) stainless steel. The lens and lamp housing (optical assembly) shall be sealed mechanically without the use of chemical sealants. Entry to the light housing shall be by means of conduit or watertight cable compression fitting(s). The manufacturer shall include silicone-filled wire nut connectors for use by the installer for watertight connections.

 
The LED lighting circuits shall be remotely dimmable by means of a heliport controller designed and produced by the lighting manufacturer. Option -VB: For use with the PHC-61002 or PHC-61003 adjustable brightness heliport controller, this option is required. The PHC Heliport Lighting Controller shall incorporate an IEC approved surge suppressor and current limiting circuit breakers on each load output.

  
The LED light shall have a tested and verified power consumption not to exceed (see power consumption below).

 
The light casting shall be powdercoat painted aviation yellow• for corrosion resistance certified by the manufacturer to comply with the US Military Standard Salt Fog Test conducted per MIL-STD-81 OF, Method 509.4, Procedure I, paragraph 4.5.2. All hardware shall be stainless steel. The outer glass lens shall be smooth and rounded to reduce the adhesion of dirt, ice and snow. The glass shall be clear to maximize light transmissivity.

  
The unit shall be warranted to withstand an ambient temperature range of:

+ 130 deg F ( +55 deg C) to -67 deg F (-55 deg C).

  
*Option -MT: The fixture shall be treated for marine conditions by cleaning per US Department of Defense TT-C-490 method Ill, pretreated with chrome-free aluminum conversion coating per US MIL-C-5541 type II, epoxy powder base coat primer and glossy polyester powder coat finish in color RAL 6003 (FED-STD-595 color #14097) dark green. Powder coating per US Department of Defense MIL-PRF-24712A type VI and oven cured.

  
The color emitting LEDs shall meet the chromaticity requirements of US MIL-C-25050. The high output LED's shall be the latest technology providing uniform light output. The LED average life shall exceed 100,000 hours. The LEDs shall be soldered in a factory set position to insure consistent light output. Wire mounted raised LEDs that can be bent out of position shall be unacceptable and cause for rejection. The LED board shall be treated with a protective dielectric conformal coating for protection from moisture and corrosion.

        
The power supply board shall include short circuit and open circuit protection and the unit shall be protected from line surges by metal oxide varistors (MOVs). There shall be a clear design element for the dissipation of LED heat to insure the LEDs do not fail prematurely. Note: It is strongly recommended that the circuit also be directly protected by a Point Lighting Corporation surge suppression device such as in a PHC, SPU or PRC unit.

       
Note: The standard PRL-97704 without -PLB option requires a minimum opening in the helideck of 5.9-inches (150mm) diameter either square per side or round diameter.

  
Option -CL: The fixture shall be supplied with a watertight cable gland and a 1.5 meter jacketed SO cable.

 
Option -PLB: The PLB aluminum mounting base shall have two (2) 1-inch NPT conduit hubs located at 0 & 180 degrees near the bottom of the 10-inch (254mm) deep base. Requires a minimum 8.125-inch (207mm) per side square opening or minimum 8.75-inch (222mm) diameter round opening.

 
The LED aviation inset light shall be POINTSPEC Series PRL-97704 manufactured by Point Lighting Corporation. 

  

        

   

 

Option-NC: Add 1.0 watt and 1.1 VA

        

*Power consumption for AC units includes the effect of the unit's power factor which accounts for the difference between watts and volt-amperes. Measurements were made at the nominal AC voltages. The operating range for 120v units is 93 - 144v. The operating range for 220v units is 176 - 250v.
  
Point Lighting Corporation recommends return for factory repair and refurbishment of LED PRL lights
