商品描述

Vanity lights on the sides of the mirror provide good lighting.
Vanity Lights

Many bathrooms have a single fixture positioned above the vanity, but a light source in this position casts shadows on the face and makes grooming more difficult. Light fixtures on either side of the mirror is a better arrangement. For a remodel, mark the mirror location, run cable, and position boxes before drywall installation. You can also retrofit by installing new boxes and drawing power from the existing fixture. The light sources should be at eye level; 66" is typical. The size of your mirror and its location on the wall may affect how far apart you can place the sconces, but 36" to 40" apart is a good guideline.

How to Replace Vanity Lights in a Finished Bathroom
Tools & Materials

Drywall saw, drill, combination tool, circuit tester, screwdrivers, hammer, electrical boxes and braces, vanity light fixtures, NM cable, wire connectors, eye protection


Step 1

Turn off the power at the service panel. Remove the old fixture from the wall, and test to make sure that the power is off. Then remove a strip of drywall from around the old fixture to the first studs beyond the approximate location of the new fixtures. Make the opening large enough that you have room to route cable from the existing fixture to the boxes.

Step 2

Mark the location for the fixtures, and install new boxes. Install the boxes about 66" above the floor and 18" to 20" from the centerline of the mirror (the mounting base of some fixtures is above or below the bulb, so adjust the height of the bracing accordingly). If the correct location is on or next to a stud, you can attach the box directly to the stud; otherwise you’ll need to install blocking or use boxes with adjustable braces (shown).

Step 3

Open the side knockouts on the electrical box above the vanity. Then drill 5 ⁄8" holes in the centers of any studs between the old fixture and the new ones. Run two NM cables from the new boxes for the fixtures to the box above the vanity. Protect the cable with metal protector plates. Secure the cables with cable clamps, leaving 11" of extra cable for making the connection to the new fixtures. Remove sheathing, and strip insulation from the ends of the wires.

Step 4

Connect the white wires from the new cables to the white wire from the old cable, and connect the black wires from the new cables to the black wire from the old cable. Connect the ground wires. Cover all open boxes, and then replace the drywall, leaving openings for the fixture and the old box. (Cover the old box with a solid junction box cover plate. )

Pellentesque Blandit

Install the fixture mounting braces on the boxes. Attach the fixtures by connecting the black circuit wire to the black fixture wire and connecting the white circuit wire to the white fixture wire. Connect the ground wires. Position each fixture over each box, and attach with the mounting screws. Restore power, and test the circuit.

梳妝燈

許多浴室在梳妝台上方只有一個燈具，但這個位置的光源會在臉上投下陰影，使得梳妝變得更加困難。將燈具安裝在鏡子的兩側是一個更好的安排。在重新裝修時，標記鏡子的位置，布線，並在安裝乾牆之前安裝電箱。您也可以通過安裝新的電箱並從現有燈具引入電源來進行改裝。光源應該位於眼睛的高度；66英寸是典型的。鏡子的大小及其在牆上的位置可能會影響壁燈之間的距離，但36到40英寸之間是一個不錯的指導範圍。

如何在已完成的浴室中更換梳妝燈

工具與材料

乾牆鋸、電鑽、組合工具、電路測試儀、螺絲刀、錘子、電箱和支架、梳妝燈具、NM電纜、接線端子、眼部保護裝備

步驟 1

在服務面板上關閉電源。從牆上拆下舊燈具，並測試以確保電源已關閉。然後從舊燈具周圍的乾牆上移除一條條帶，直到新燈具大約位置的第一根木樁。確保開口足夠大，以便從現有燈具引導電纜到電箱。

步驟 2

標記燈具的位置，並安裝新的電箱。將電箱安裝在距地面約66英寸，距鏡子中心線18到20英寸的位置（某些燈具的安裝基座位於燈泡的上方或下方，因此相應調整支架的高度）。如果正確的位置在木樁上或旁邊，您可以將電箱直接固定在木樁上；否則，您需要安裝阻擋物或使用帶可調支架的電箱（如圖所示）。

步驟 3

打開梳妝台上方電箱的側面開口。然後在舊燈具和新燈具之間的任何木樁中心鑽5/8英寸的孔。從新電箱引入兩條NM電纜到梳妝台上方的電箱。用金屬保護板保護電纜。用電纜夾固定電纜，留出11英寸的多餘電纜以便連接到新燈具。去除護套，並剝去電線末端的絕緣層。

步驟 4

將新電纜的白色電線連接到舊電纜的白色電線，並將新電纜的黑色電線連接到舊電纜的黑色電線。連接接地線。覆蓋所有開放的電箱，然後更換乾牆，留出燈具和舊電箱的開口。（用實心接線盒蓋板覆蓋舊電箱。）

步驟 5

在電箱上安裝燈具安裝支架。通過將黑色電路線連接到黑色燈具線，並將白色電路線連接到白色燈具線來安裝燈具。連接接地線。將每個燈具放置在每個電箱上，並用安裝螺絲固定。恢復電源，並測試電路。
