TORRANCE, CA — December 6, 2001 — Continuing to innovate on its offerings of direct incandescent replacement LED (light
	    emitting diode) lamps for process-control and machine status-indicator towers,
	    LEDtronics today announced the availability of StackLED® SMT LED lamps.
	    These lamps are manufactured using SMT (surface mount technology) processes
	    and incorporate 1206-profile SMT LEDs, resulting in StackLED lamps with
	    unprecedented brightness and reliability. Automated SMT fabrication enables
	    more LEDs to be placed on a printed circuit board with greater efficiency
	    and precision than possible with manual assembly. With a typical operating
	    life measured in years not hours, StackLED SMT lamps provide substantial
	    savings in maintenance and relamping along with the essential non-interrupted
	    flow of information between machine and man. 
StackLED SMT lamps are ideal for indicator light towers on conveyor systems, pick-and-place assemblers,
	      automated surface mount machines, process control lines and high-noise
  industrial environments. StackLED SMT lamps are plug-compatible with most major
  manufacturers' stack light towers, require no modification to the indicator column,
  and can be used with flasher circuits. With a wide choice of sizes, standard
	      electrical bases, six sunlight-visible colors, industry-standard voltages,
	      there's a StackLED SMT LED lamp to meet your requirements. StackLED
  SMT lamps have double-sided printed circuit boards that have from 4 to
  24, depending on the model, SMT LEDs on each side to provide 360-degree viewing.
  Electrical
	      bases available are 15mm DC bayonet, 9mm miniature bayonet, candelabra
  screw and wedge based. Polycarbonate globes protect the printed circuit boards
	      from impact and environmental conditions while optimizing viewing and
  dispersing
	      light. StackLED lamps come in all standard voltages (12V, 24V, 120V)
  AC or DC as well as AC/DC bipolar. StackLED lamps retrofit to a specific manufacturer's
	      stack holder and are designed specifically to operate in those models.
  Choose
	      from six sunlight-visible LED colors: Red (660nm), Orange (610nm),
  Yellow (595nm), Aqua Green (525nm), Blue (470nm) and White (8000K).
	    Incorporating state-of-the art LED technology, design and assembly, SMT
	    StackLED lamps are built to withstand the mechanical (vibrations) and electrical
	    stresses (fluctuations) that exist in the industrial environments where
	    vertical indicator towers are commonly used. With an average life span of
	    100,000-plus hours (11 years), LED lamps operate more than 20 times longer
	    than the equivalent incandescent lamp! Solid-state design renders LEDs impervious
	    to shock, vibration, frequent switching and environmental extremes. Savings
	    from reduced maintenance costs and downtime quickly return the investment
	    expenditure, which are important factors to consider when evaluating the
	    financial aspects of installing LED lamps. 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, LEDtronicsâ 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
	    LED Lamps, low-cost snap-in and relampable Panel Mount LED Lamps, 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 StackLED SMT LED Lamps range from $19.68 - $68.88 each in
	    quantities of 50 depending on LED technology and model type. For additional
