A couple of years ago I extended my workshop and wanted really good lighting. I discovered Yujileds and installed 5 metres of CRI 95+ 5600K around the edges of the ceiling to reduce shadows.
These LEDs are more expensive for a reason: No flicker, the light is operating-theatre quality and colours are rendered exactly as they do in sunlight.
A month before the guarantee expired the remote control of the dimmer failed. I contacted them and after exchanging a couple of emails, a very helpful Queran sent me a new remote control and dimmer, which arrived by DHL a few days afterwards, free of charge.
Summary: Brilliant lights (forgive the pun) and excellent after-sales service. Highly recommended.
