Reduction Revolution is an online store that specialises in energy efficiency. We sell products to reduce energy usage, improve comfort, save time, and cut costs.

One of our most common downlight questions is "how many downlights do I need?" To answer this question, you need to know three things:

IP69K washdown backlight bars provide high brightness, highly diffuse illumination in a reliable package designed to withstand the rigours of harsh chemical cleaning & de-contamination.

LED downlights are mostly used to achieve the 'General Lighting' or 'Task Lighting' brightness levels below. For other applications, you may be better off with a different type of LED light.

Adafruit Industries, Unique & fun DIY electronics and kits Fiber Optic Light Source - 1 Watt - White : ID 4168 - This is a pretty neat way to glow up.

Combined with our Angle Changers, the Modular Bar can be configured to suit almost any machine vision application. Our products help thousands of customers globally to effectively and expertly illuminate industrial automation and logistics applications across many industries, from pharmaceutical, food and beverage manufacturing to the automotive industry, and much more.

The Backlight BLBAR+ is a very powerful lighting solution, equipped with an opaque diffuser that offers a perfect diffusion of light on the whole surface, all the way to the edges. No hot spots to be seen! It’s the best addition to your camera for all machine vision inspection applications. The Backlight BLBAR+ is usually used as a traditional backlight, to make the workpieces’ outlines appear with high contrast, but it can also be used as a direct diffuse light. Its rugged packaging enables efficient LED heat dissipation. The Backlight BLBAR+ is IP65 by default. 2 LED indicators near the connector show if the product is powered. As with any other TPL Vision bar lights, users also benefit from its solid aluminium structure and its easy fixing.

Using the above downlight calculator, here are some example results with our most popular LED downlights. See if you can replicate them or adjust them for your own lighting needs:

The Essential EBAR+ is a highly powerful LED light, very useful for machine vision applications requiring intense luminous flux. It can be set up downwards, in the same axis as the camera’s, or with an angle of incidence, to perfectly illuminate rectangular areas on a production line. The Essential EBAR+ is very easy to use: you don’t have to adjust anything, only to plug it. There are 2 functioning modes: continuous and strobe, with very short rising and falling times (15 μs and 10 μs). Its black aluminum structure, very robust, is IP65. It also helps to dissipate the heat generated by the LED. Moreover, 2 LED indicators near the connector show if the product is powered. Available in different colours (included IR and UV), the Essential EBAR+ exist in multiple lengths, from 125 mm to 1250 mm (Standard/Link) and up to 2500 mm (OverDrive).

This is where the following downlight calculator comes in. You can enter the lumens of your chosen LED downlight, the area of the space, and then estimate the number of fittings required. Our lighting calculator will display the average light intensity produced (lux).

Connect up to six lights in a line without loss of uniformity. NanoDrive allows the light to be fully on in less than 500ns.

Alternatively, for samples which scatter light, absorbance may be defined as "the negative logarithm of one minus absorptance, as measured on a uniform sample".

TPL Vision’s bar lights made of high-power LEDs come in various sizes and colours to help create the best contrast for image processing. These linear lights are extremely versatile and can be used to create different lighting techniques (bright field, dark field, dome effect) suited to automation and robotics applications. Due to their flexibility, TPL Vision’s bar lights simplify the product selection process and guarantee easy integration. Our extensive range contains products dedicated to logistics, washdown food & beverage and UV fluorescence applications.

The total light output of a downlight bulb or fitting is specified in lumens. Light intensity, on the other hand, is measured in lux.

Miniature modular bar light with built-in flexibility. The M-TBAR is a compact, IP67-rated tiny LED bar light that allows users to change the beam angle with TPL Vision’s Angle Changers. Offering unparalleled flexibility, the M-TBAR provides a convenient way to expertly illuminate small-scale vision applications requiring a robust lighting solution. Application areas include code reading, quality control, component verification, label- and packaging inspection, robotics and more.

UV INFO: in the light spectrum, UV (ultra violet) rays are electromagnetic radiations situated between 280 and 400 nm (visible radiations: between 400 and 800 nm). What makes UV very interesting is the fact that, even if it is invisible for the naked eye, it can be observed by fluorescence: when some bodies are submitted to UV wavelengths, they emit a visible light. This is the principle of black light and of counterfeit notes detection.

The XBAR RGB provides uniform and powerful lighting in a variety of colours. It is a versatile product that is especially useful when controlling a wide range of colours, shapes, and materials. The XBAR RGB is equipped with a solid body made of anodised aluminium and can work in continuous or strobe mode. It is recommended for robotics applications, particularly the palletization process, as well as packaging inspection (for the cosmetics and food industries), where the product’s colours and materials may change on a regular basis.
