About the J4 Series

The J4 series LED tube is more superior than our J1, J2 and J3 range. It is made from both Aluminium and Polycarbonate (PC) and has a beam angle of 180°. This is mid brightness and is 115lm/w and works direct from the AC mains or with a magnetic ballast but you must substitute the fluorescent starter for the LED starter which is supplied with each tube. It has a wide voltage range (AC85-265V 50-60Hz) allowing it to work with every application. We have a number of SMD2835 inside depending on the lamp length. The cover is frosted and specially treated to make the LEDs invisible.

A nice feature in this range is the ability to change the colour of the end cap. You can personalise your range by choosing one of nine colours should you wish it. The end caps are also rotatable.
