MAINTENANCE
BULB REPLACEMENT PROCEDURE
Every new EC-Series Flood Lamp is supplied with a new 400 Watt Bulb. When the Bulb requires replacement,
the following procedure must be followed.
1. Turn the Power Switch off.
2. Disconnect the Power Supply from the electrical power source.
3. Allow the Bulb to cool.
CAUTION: The Bulb operates at temperatures exceeding 500°C. Touching the Bulb before sufficient cooling
may cause severe burns.
CAUTION: Always wear safety eye wear while replacing Bulb.
4. Hold the Lamp/Reflector Assembly Housing securely and loosen thumbscrew on the Lamp/Reflector
Assembly Housing Bracket. Lift the Lamp/Reflector Assembly Housing off the Mounting Stand and place
upside down on a clean work surface.
5. Reach into the Reflector and grasp the flat area of Bulb at either end (Figure 17).
CAUTION: Always use a soft, clean rag, clean paper towel, or gloves when handling the Bulb. Skin oils left
on the Bulb will burn into the quartz, reducing output intensity. If the Bulb is inadvertently touched, clean the
Bulb thoroughly with a soft, clean rag and alcohol.

6. Lightly push the Bulb toward the Lamp Socket on the opposite end of the Bulb so that the end being grasped
can be lifted clear of the Socket as shown in Figures 18 and 19.

surface. Avoid touching the quartz tube with your fingers.
NOTE: Bulb has no polarity.
