3  LAMP OPERATION 

3.1  POWER 

AC 

Operation of the Q-LED II requires an input voltage between 0 

– 120VAC 50/60Hz. The 

lamp  draws  150  VA  of  power  at  maximum  light  intensity.    Maximum  light  intensity  is 
measured at 120 VAC.  They begin to output light at 70 VAC (typical). 
 

DC 

Although the Q-LED is intended to be an AC powered light, it can also be powered by 
DC power. The 120 VAC version can run off of DC power from 0-160 VDC. Maximum 
light intensity is measured at 160 VDC.  They begin to output light at 95 VDC (typical). 
 

3.2  TEMPERATURE PROTECTION  

The  Q-LED  II  is  electronically  protected  from  overheating  via  a  thermal  cut-off  switch. 
The light will run for approximately 4 minutes in air (at an ambient temperature of 20°C 
(68°F))  before  automatically  powering  down.  There  is  no  reset;  the  light  will 
automatically re-illuminate once it has cooled to a safe operating temperature. 

3.3  RECOMMENDED OPERATION 

The  thermal  protection  is  intended  as  a  failsafe  feature  to  protect  the  light  from 
unintentional damage from extended use in air.  It is not recommended to  intentionally 
run the light out of water for any extended period as it will reduce the product lifespan.
