LEDs. What Do I Need To Know?

We recently caught up with Hanspeter Eiselt, Director of, and he gave us a quick run down of what we need to know when buying LEDs.

What are LEDs?

LEDs, or Light–Emitting Diodes, are semiconductor devices that produce visible light when an electrical current is passed through them.

LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).

LED Shapes

LED Globes come in a wide variety of shapes like the existing incandescent and halogen bulbs They come in candle shapes for chandeliers, recessed down lights and many more.

LED Globes require 80% less energy without sacrificing light output. A 12.5W LED globe replaces a 75W incandescent bulb, popular 60W bulbs can be replaced with a 9.5W LED globe, 25W candles with a 4W LED candle. 5.5W MR16 LED replace 35W Halogen.


LED Globes fit in the same sockets as the traditional bulbs did, thus making it easy for anyone to replace a light bulb. LED Globes come with Bayone caps (B22 or SBC), Edison Screw (E27,E14), GU10, MR11 and MR16 for low voltage halogen replacements.


LEDs used to only produce cool-white (4000K) or daylight (6500K) light.

This was corrected with new LEDs which have warm white (2700K/3000K) colour temperature closest to Incandescent bulbs.

Do It Yourself (DIY)

LED globes fit into the existing sockets like Bayonet, Edison Screw, GU10 or MR pins.They are installed as you did before. Only in few cases is the help of an Electrician needed.


Whilst LED globes are slightly dearer than traditional globes, most LEDs last 15+ years (assuming 3hrs/year usage). This is 15x times longer than incandescent bulbs. A lot less maintenance!

Many thanks Hanspeter for these handy tips!
