it  is  still  working.
•Do  not  repeatedly  turn  off  the  power  and  immediately  back  on.  Turning  the
power  on  and  off  frequently  may  shorten  the  lamp's  operating  life.
•Depending  on  the  characteristics  of  the  lamp  and  the  way  it  has  been  used,
the  lamp  may  become  darker  or  stop  working  before  the  lamp  warning
