I have over the last 2 years interviewed Ian Muir from Gekko during IBC and the LED lights from Gekko are not only good they are made in the UK. HD Warrior has a policy to show off the best of British when it comes to video technology and ancillary equipment.
Two lights stand out the Kisslite (seen above on ARRI camera) which is a fantastic LED ring light that gives you an even light on an actors face, especially good for Steadicam usage.
Secondly the Kelvin TILE a pure bit of genius, this light can produce not only pure white light but primary colours as well making it extremely useful for interview work or pack shots.
I hope to get some sample LED lights from Gekko to produce a video review but till then you can take up a smashing offer from CVP on the Kelvin TILE LED light which is more than competitively priced against imported LED lights from China and the USA.
