[lm-announce] Switching lamps on and off...

[Sam Swift]

Dear All,

Could I please remind you all that switching the fluorescence lamps  
on and off in quick succession reduces the lifetime of the bulb and  
increases the risk of the bulb exploding (believe me - you don't want  
to be around when that happens).  If you turn a bulb off just before  
the next user starts, it is a big waste of their time to have to wait  
before they can switch it on again.  This happened 3 times last week  
and there were some seriously stroppy people wandering around asking  
me to crack some skulls.

With this in mind, please memorize the 4 rules of fluorescence lamp  
etiquette -

1.  Leave the bulb on for 1 hour after you have turned it on.  If you  
use the microscope and discover your sample just ain't working, don't  
switch the bulb off unless it has been on for an hour already.

2.  Make sure the bulb has been switched off for an hour before you  
turn it back on again.  When you finish your session, please check  
the webcalendar to see when the next person is going to start.  If it  
is within a couple of hours of your session finishing, please leave  
the bulb ON.  If you finish your session early, it is polite to let  
the next user know the microscope is available early.

3.  Let us know when the bulb is approaching 375 hours of use.  The  
bulbs need to be replaced at approx 400 hours, so please give us a  
bit of notice on this.

4.  When a bulb is replaced it needs to be left on for 24 hours to  
"bed in".  When we change a bulb we will write in the logbook when it  
can be turned off again, but obviously if you are on the scope and  
the lamp reading is at less than 24 hours, you'll need to leave it on.

Thanks!
Sam
