Select the type of lighting
LED
Economical due to low power usage and no bulb to change (minimum working life of 50,000 hours), no heat output, “unlimited” number of on/off cycles.
Excellent luminous efficacy (lumen per watt).
HALOGEN
Economical to buy, excellent colour rendering (CRI 100/100), warm colour temperature, but high heat output and power use.
Low luminous efficacy (lumen per watt).
INFRARED
WOOD
Ultraviolet diagnostic light (black light).

Customize your lamp
For many of our lamps you can choose different flexible arm lengths, the colour (black or white) and the switch type (on/off, dimmer, or “contactless”).
