What is IK Rating?

IK Rating is representative of the protection provided by the enclosures of electrical systems against mechanical impacts in accordance with IEC 62262:2002 and IEC 60068-2-75:1997. It is on a scale of 0 – 10, with 10 representing the largest rated protection against actions such as dropping tools onto the enclosure, dropping the enclosure and hitting the enclosure. The table below outlines the qualities of each degree of protection. IK Rating Degree of protection IK00 No protection IK01 Protected against 0.14 joules impact. Equivalent to impact of 0.25 [...]

What is IP Rating?

IP Rating (International Protection rating sometimes called Ingress Protection Rating) defines the level of protection against intrusion or the sealing effectiveness against body parts, dust, water and accidental contact by electrical enclosures. A units IP rating is usually made up of two digits; the first digit denotes the intrusion protection and the second digit denotes the moisture protection. Number First Digit (Intrusion Protection) Second Digit (Moisture Protection) 0 No special protection. No protection. 1 Protection from a large part of the body such as a hand (but [...]

Differences in Constant Current Vs Constant Voltage LED Lighting Systems

Differences Constant Current Vs Constant Voltage LED Lighting Systems.   Constant Voltage Lighting systems are generally connected in Parallel as per diagram 1: Constant Current Lighting systems are generally connected in Series as per diagram 2: The most common step up for new downlights is the Constant Current set up. This is because internally with the downlight head the LED’s are connected in series as per diagram 2. The major advantage with this configuration is it provides the best lighting output per watt usage. However the disadvantage is that one faulty LED chip could potentially cause the lighting system to fail, however this situation is very rare due to the reliability of LED chips. One [...]

12 Volt Pendants for Caravans

Most pendants lights come with E27 socket where usually only 240V E27 lamps can fit. Now recently a new range of LED 12V DC 7 lamps have hit the market. These are shaped identical to the classic bulb but only operate on 12V making them ideal for caravan lighting. They are available from 4W to 12W and warm white or cool white and therefore can fit any mood. Browse our full range of E27 bulbs here.

Selecting the Correct LED Strip Voltage

LED strips come in different voltages, just like for a car. In a car, the battery is a 12V DC and therefore all other DC equipment such as the car radio also runs off 12V. Most trucks run a 24V DC battery, so ther light systems and other systems must be able to run off 24V. LED strips commonly come in a 12V DC design. However, once we reach 5 metres in length, the strips will start losing brightness. This [...]

Garden Lighting using 12 Volt E27 or MR16 LED Lamps

You don’t need to run 240 Volt cabling for garden lighting because using lower power LED lights are safer due to the low relative voltage. There is now a new range of 12 Volt E27 lamps available in warm white and cool white colours. These are excellent choices when selecting E27 base bollards. With E27 base bollards there are an abundance of styles of choice to suit your garden. Connection is simple with a 12V driver or transformer.
