I don't think you will be interested at £30 each but here they are...

Pretty big units made by Philips. You can get them in a number of different beam angles (25 and 40 degrees). These are 7W.

The Philips master range is pretty good. There are loads of different shapes, fitting types, colour (whiteness) and Wattage. Just a few are pictured below...





Another alternative that you have if you want to go dimmable is to go fluorescent. I bought some fluorescent ones to see what they were like... they gave a very good bright light BUT took about a minute to warm up. I have now put them in the chippy as the 1 minute start up is fine. The dimmable fluorescent are around £15 for an 11w and they last about 15,000 hours.
