40 W Metal Swing Arm Desk Lamp

This 40 watt metal desk lamp uses an adjustable swing arm that extends up to 18 inches and a rotatable base and shade. It can stand on its weighted base or clamp to surfaces up to 2 inches thick with the included C clamp. The E26 E27 socket accepts A19 or G25 bulbs sold separately.

UL Listed Plug and Rocker Switch

The lamp ships with a 55 inch power cable and an on off rocker switch for daily use. The UL listed plug meets safety standards. No integrated LED module is included so heat output and power draw depend entirely on the chosen bulb up to the 40 watt rating.

Replaces Fixed Position Desk Lights

Buyers who need to reposition light across a wide desk or workbench gain the spring balanced arm and rotatable joints. Builders who want a fixture with a built in LED array or a higher maximum wattage will need a different model.

Questions about this item

How do I install the clamp so it grips a desk edge securely?

Open the C-clamp wide enough for surfaces up to 2 inches thick, tighten the screw until the rubber pads press firmly, then verify the weighted base sits flat before extending the arm.

Which replacement bulb should I buy when the original burns out?

Use an A19 LED bulb with an E26 base — 5.5 W, 450 lumen, 120 V — in 3000 K warm white, 5000 K daylight or 2700 K soft white; G25 is also compatible.

How far can I stretch the arm before it starts to sag?

The spring-balanced arm extends to 18 inches; beyond that the counter-weight can no longer hold the shade level and droop appears.
