Panel Mount LED Lamps and Holders Save Maintenance Costs by Outlasting Incandescents 20 to 1

Torrance, CA — June 23, 1999 — Continuing to expand its offerings of based LEDs for OEM and retrofit panel mount applications, LEDtronics introduces 16mm, 22mm and 30mm direct incandescent replacement RPLH Series Panel LED Pilot Lamps and Holders. The RPLH Series Pilot Lamps and Holders are an integrated modular system that may be purchased as complete assemblies, which incorporate the lens, lamp and lampholder, or as separate components.

With behind-the-panel depths ranging from .93-inches to 1.04-inches and sunlight-visible light colors, the RPLH Series is excellent choice for applications where space is a concern and aesthetics a consideration. RPLH Series Lamps and Holders can be employed in utility monitoring boards, industrial control equipment, audio and intercom panels, broadcast equipment, nuclear power status stations and medical instrumentation.

Like the incandescent bulbs commonly used in panel mount applications, LEDtronics’ RPLH Series LED lamps feature T3¼ (9mm) single-contact miniature bayonet bases that give installation a familiar twist. RPLH Series LED lamps are rated for 28V DC. They directly replace 28MB, 313, 757, 1819MB series incandescent bulbs. Light colors available are red, orange, yellow, green, blue and white. All colors are sunlight visible!

Raised Lexan® fresnel lenses resist impact, provide an optimal viewing angle of 180° , maximize light dispersion and come in a variety of colors. Designed for screw-on mounting, lenses are independent of the lamp fixtures enabling them and the LED lamps to be easily changed. RPHL Series lamp holders are made of rugged, black Ryniteâ polyester resin (UL class UL94V0, UL listing E110075) that withstands the rigors of industrial environments and provides view-enhancing contrast. Holders incorporate captive terminal screws with self-lifting, pressure wire clamps that accept up to two 14-gauge wires. Lamp holders are rated for incoming voltages of 48V DC and 130V DC. Compact RPHL Series holders fit many space-restricted applications with behind-the-panel depths of .94", 1.04" and .93" for 16mm, 22mm and 30mm fixtures, respectively.

The RPLH Series LED lamps’ solid-state design renders them impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. With an average life span of 100,000-plus hours (11 years), RPLH Series LED lamps operate reliably year after year. That’s more than 20 times longer than the equivalent incandescent lamp! Savings from reduced maintenance costs and downtime quickly return the capital investment expenditure! Additionally, RPLH Series LED lamps produce almost no heat and require 80% - 90% less operating power than equivalent incandescents, making them as friendly to the environment as they are to the operating budget.

Founded in 1983, LEDtronics® leads where others only follow when it comes to designing, manufacturing and packaging state-of-the-art LEDs to meet the world’s constantly changing lighting needs. Our inventive product line encompasses an array of direct incandescent lamp replacement Based LEDs, low-cost snap-in and relampable Panel Mount LEDs, high intensity sunlight-visible Discrete LEDs, PCB LEDs circuit board status indicators, surface mount diodes SMT LEDs, full-spectrum rainbow RGB LEDs and Infra-Red (IR) LEDs.

Prices for RPLH Series Panel Pilot LED Lamps and Holders range from $26.75 - $36.50 each depending on the holder size and choice LED color.
