Well lights and PAR36 uplights aimed at mid-size shrubs, stone walls and small trees are where the CLS LL366 fits best. This 6 watt PAR36 lamp delivers 590 lumens, and CLS lists it as the stand-in for a 35 watt halogen PAR36.
What input voltage does the LL366 take?
The CLS price list rates this lamp at 12 to 24 volts AC, the same as the 10 watt LL3610. The 13 and 17 watt lamps in the series are listed at 9 to 17 volts AC, so confirm your transformer taps if you plan to mix wattages on one system.
Is 6 watts enough, or should you move up to 10?
For a feature you would have lit with a 35 watt halogen, 590 lumens is the matching choice. When the tree is taller or the wall wider, the LL3610 raises output to 800 lumens. The 13 and 17 watt lamps, at 1130 and 1300 lumens, are meant for large trees and big facades.
Which options do you pick when ordering?
Choose a 38 degree beam for a focused uplight or 60 degrees for a broader wash, and 2700K or 3000K for color. The die-cast aluminum housing is waterproof, thermo protective and rated IP67, with a 50,000 hour L70 life.
