These are available from a variety of sources often more expensive. One slight
issue is the light
of "white" LEDS has a large peak in the blue, so colors are off a bit without
added filtration.
I built something more like a t18 for my microscope, using two high wattage
(3W) lumileds (like
the ones they use in high power LED headlamps or bikelights now) and a cheap
power supply.
Unfortunately the Lumileds with their small integrated reflectors, were pretty
expensive from the
only distributor I could find.
Sometimes it is good to have shadows and sometimes not, to see 3d effects.
Having seperate
adjustable lights gives some options.
