Your bulb should last up to 10,000 hours in normal use. When bulb 
replacement is necessary, you must replace the bulb with a 
self-ballasted GU24 base fluorescent bulb. These bulbs are readily 
available at  your local home center and most larger hardware stores. 

Remove the old bulb by grasping it 

firmly at the plastic base of the bulb 

and firmly twist the bulb counter- 

clockwise until it “unseats” and lines 

up with the large end of the 

openings (Fig. 3). Pull straight down. 

Be careful not to drop the bulb. 

Grasp the replacement bulb in 

the same manner and re-insert 

the replacement bulb into the 

socket and twist the bulb 

clockwise until it ‘seats’ (Fig. 4). 

Do not force the bulb into the 

socket or twist forcefully.

Restore power to the fixture.

Shut off power supply. Allow sufficient time for bulbs to 
cool properly before handling.

2

Remove the fixture’s diffuser by removing the Philips screw.

Minor problems often can be fixed without the help of an electrician. Before doing

any work on the fixture, shut off power supply at the circuit breaker panel to avoid 

electrical shock.
