Dialight Problems with Existing Technology

• High power consumption • Short life

• damaged solder connections of the contact pins • filament burn out • broken electrodes • cracked glass

• EMI/RFI interference • Poor optical control = light pollution

Dialight Advantages of LEDs

4

Dialight Advantages of LEDs

• Solid-state semiconductor technology

• Smallest light source available

• Mercury & lead free material (RoHS compliant)

• No fragile glass

• No fragile filament

• No corrodible contacts

• Shock and vibration resistant

• Long life (can last more than 100,000 hours)

LEDS are the most efficient white light source

Dialight LEDs = Reduced Voltage

LEDs: No high voltages

HAZARD WARNING

Equipment may generate dangerous voltages. Exercise extreme caution at all times when operating, maintain, or servicing.

AVOID TOUCHING LIVE CIRCUITS

Avoid touching any component or any part of the circuitry while the equipment is operating. Do not change components or make adjustments inside the equipment.

DANGEROUS VOLTAGES CAN PERSIST EVEN WITHOUT POWER

Capacitors can retain high charges.

Xenon systems

1,000 volts

or more

LED systems

150 volts

or less
