One property can need a soft accent on a boxwood hedge and a strong uplight on a mature oak. The CLS IUL01 handles both with an integrated LED in a solid cast brass housing whose brightness adjusts from 2 to 12W, so a single model covers most of the scene.
How bright does a 2 to 12W up light get?
CLS publishes a range of 240 to 840 lumens. The low end suits shrubs, grasses and small specimen plants, while the high end reaches up into a large canopy. Setting the output at the fixture lets you balance a scene on the night you aim it, without swapping hardware.
Is a brass housing worth it for an up light?
Brass resists corrosion and draws heat away from the LED, and its finish ages along with the landscape. This one comes in Antique Bronze, sealed with dual silicone O-rings and rated IP65, which suits irrigated beds where fixtures stay damp.
Which beam should I choose?
CLS lists 24 and 38 degree beam spreads. Go narrow for tall trunks and wider for broad shrubs or wall sections. Color rendering is CRI 85.
