How about a CFL bulb (the twisty ones!)? If you get one with a Colour temperature of 5000 degrees Kelvin (maybye marked on the package) it would show the colours of the flowers better. Can you buy LED bulbs there yet - could be expensive.
BTW, did anyone notice that the spell check on this board tells you that colour is incorrect and that color is correct???
Maybe I didn't see a setting???
Rock on..................
