Optional Stone guard.
An optional stone guard (order suffix /SG) is available for the Type 2020 illuminator. Designed to
protect the filter from flying objects / vandalism the guard can be fitted in seconds with 4 off fixings
supplied. (fig.13)
Optional Voltage reducer.
The Manufacturers stated life expectancy for the 300W bulb is 2000 hours and 4000 hours for the
500W. This stated life is conditional on the supply being 230V, a 5% increase in voltage will reduce
lamp life by 50%.
NB. There are some parts of the UK where the standing voltage is over 250V, in a situation
such as this Dedicated Micros can supply a Type 621 voltage reduction device which will
reduce the incoming supply by 9% to increase the bulbs life. (fig.14) Box dimensions 110W x
