PRODUCT DETAILS
Description
Give an existing bedside lamp a red light option
Use this A19 red LED bulb in a compatible nightstand or table lamp to add red light near the bed. It suits setups where the bedside lamp is used separately from the overhead light. Try it in a shaded lamp next to the bed or in a lamp directed toward the wall. The shade and the lamp’s position will affect how much of the red light reaches the bed and surrounding furniture.
Choose red for the look you want at the bedside
Use the red bulb when the desired result is a distinctly red glow. If the same lamp will also be used for reading, check a sample with the intended shade and a typical book. Colored print can look different under red light, so test both black text and color illustrations if reading is part of the intended use. For a product range that covers several evening lighting preferences, the amber bulb gives buyers a separate golden light option.
Match the bulb to the fixture
Check the lamp’s screw socket, voltage and available space inside the shade before fitting the bulb. Switch the lamp off before replacing the bulb. Once installed, check the light with the shade in place and from the position where the lamp will normally be used. For a dimming setup, verify the bulb and dimmer combination for the version you plan to order.
