What is Base Up
Base up describes a specific orientation or direction of a lighting fixture. It refers to the positioning of the base of the fixture in an upward direction. This means that when the fixture is installed, the base is facing upwards, while the light source is directed downwards.
The concept of “Base Up” is often mentioned in conjunction with other base directions, such as “Base In” (BI), “Base Out” (BO), and “Base Down” (BD). These different base directions allow for versatile lighting arrangements and can be combined vertically and horizontally to achieve desired lighting effects.

Perguntas frequentes
O que é Base In e Base Out
O termo “base” refere-se à extremidade mais espessa do prisma, indicando a direção na qual a luz é redirecionada. Esta pode ser na extremidade externa da lente (Base Out, BO), na extremidade interna (Base In, BI), na extremidade superior (Base Up, BU) ou na extremidade inferior (Base Down, BD).
What Is Base Direction on Glasses
The base direction on glasses refers to the direction in which the thickest edge of the prism is positioned. It can be indicated as BU (base up), BD (base down), BI (base in toward the nose), or BO (base out toward the ears). The base direction is important as it determines how the prism will redirect light.
What Do You Mean by Base In
Base, in the field of chemistry, refers to any substance that, when dissolved in water, has a slippery texture, a bitter taste, alters the color of indicators (such as turning red litmus paper blue), reacts with acids to create salts, and facilitates specific chemical reactions (known as base catalysis).
