I have one these lights in brown but different shape - i could've had the blue ones as it was a choice between the blue and brown. I live in New Zealand, but I think they were sourced from overseas. Check out this link - you can ask the owner, she is a great lady. https://www.facebook.com/Mr-Ralph-534507496617824/timeline/ or http://www.mrralph.co.nz/

If you go for down lights you will need to leave a gap around them of 100 mm between the recessed part and insulation so the insulation doesn't catch on fire. This also creates a problem with the thermal performance of your home because heat can move freely through the ceiling where there is no insulation. It can make a big difference even if there are only a few down lights. Also, down lights are very directional (send most of their light straight down) so you need to put more in to get the same effect. You could try track lights that attach to the ceiling instead. If you want a pendant go for something cheap and easy to replace if it is damaged by toys/clothes or whatever being thrown around. Ikea have lots. FYI dimmers don;t educe the power consumption, merely reduce the intensity of the light.

They look great in that photo, Northstar! Works beautifully. Will be fine over your bench. Didn't realise how large your p really space will be. Wow! No, if you replace pendants that have staggered drops, the fittings are completely removed and new pendant fittings are installed in their place. The electrician just shortens the drops without cutting them & the extra lenth is hidden away in ceiling.

This depends on your budget and the style you are after. Fat shack vintage has some great lights. Or Beacon or Ikea have some good choices. I've found lovely pendants from a uk website I'll be using in my next home. And we did the same for a pendant for my last place. Look around online, and get a feel for what you like. Modern? Industrial? Rustic? Mid century? Etc.
