*This type has 5-12 spectral response.
**Dissipation ratings apply up to the maximum rated ambient temperature.
+This type has a "demand rating" of 0.75 watt. This rating is a dissipation rating to which the
cell may be exposed in outdoor applications. The rating may be used twice every 24 hours for
a period of 20 minutes, each time, provided the interval between demand services is not less
than four hours.
++This type has a demand rating of 0.8 watt.
