No I'm not about to go all evangelical, well, not in the traditional sense at least. I recently spotted these interesting halogen bulbs that flood the bathroom in a cool and trendy 'W Hotel' aqua. What's interesting however is how the same bulb diffuses purple light at the perimeter and blue light at the focal.
The halogen equivalent of the two-tone chromaflare paint used by British sportscar maker TVR, I can't work out how it's done. While it may be one thing to 'accidentally' pack a hotel bathrobe, swiping light bulbs is probably the beginning of a slippery slope; inevitably leading to the liberation of several thousand pounds of hotel artwork; and a not so liberal stay at a different kind of hotel.
