There is never any pricing differences between WW or DL so this may be a pricing error? Online still showing as $79 but in-store at Kotara Bunnings for $29. Unsure if location specific or aus/state wide.

Bundle with a Clipsal sensor and you should be set! Problem is Clipsal sensors are expensive
Bought 2 of these a month ago for the same price
I have been buying these. Have bought several from 100 watt to 15 watt in both warm and cool and have been happy.
$20.99 for 30 watt. Big housing.

Would be good if it had a sensor
