1984-2024 A Brief History of Arrant-Light Oy The story of Arrant-Light Oy began in Turku, in 1984 as a supplier of long-life fluorescent tubes and bulbs. Mr. Tarmo Mäkinen established the company and together with his wife Eeva started to run it. His knowledge and long experience in managing wholesale and electrical installation companies led…
A few years ago we released our own borosilicate glass optics series named aLED ALOG100. This series contains six different glass lenses with angles from 20° to 160°. These glass lenses have so many good features, and in this blog post, you’ll understand why aLED ALOG100 is so popular and why you should really consider…
We talk a lot about energy saving in general lighting, but somehow we have forgotten that in LED strips. In this blog post, I will present a new aLED product: The aLED KIDEFLEX LED strip. It’s a new kind of LED product that can save energy up to 84%. Energy-saving in the LED Strips In…
aLED products are Arrant Light Oy’s own line of LED modules. We have been designing and producing LED modules since 2008. Our LED modules have been used for mass production luminaires and also for projects that need a special solution like in hospitals, automotive industry, safety light, and architectural lighting. We have dozens of standard LED…
We redesigned our aLED-modules based on customer and market feedback. Here is a brief explanation on what is different compared to previous version. And why I think you should consider using aLED modules. Better efficacy (159-191 lm/W) We upgraded the SMD LEDs used in the modules to better suit our customers’ needs. aLED modules…
Q:You have the driving current 700mA written in the datasheet of your LED module. Can I use smaller driving current? A:Yes, you can use smaller current. The current value 700mA mentioned in the module’s data sheet is so-called nominal/typical value that corresponds to the value Citizen announces for voltage and luminous flux (lumens) of the…
Generally, when selecting LED luminaires, the attention is drawn to energy consumption. Efficacy, therefore, the power consumption, is the most important selection criterion. But do you pay attention to the lifetime of the luminaire? What happens if the better efficacy luminaire has shorter lifetime? This means that you may have to renew the luminaires much…
In this blog post we concentrate on how to design a LED lighting package as a whole. And what different aspects you will have to take into account when selecting a light source and a driver. I decided to write this as a case example so that the post is more concrete. Most of the…
How to affect the lifetime of a LED module Lifetime of a LED module? What it means? Does it mean that LED module does not function anymore after the defined lifetime value? How to determine lifetime for the LED module? This post tries to explain what different lifetime estimation curves mean and how to interpret…
We released a new brand for our products; aLED. At first this brand is used along with our led modules, but later there will be more products to be labelled aLED. There might be some people, possibly you, wondering what does aLED stand for? And why did we decide to create such a brand? Let…
