Example of stack, produced using this light.
Custom white balance (about 3100K), 1/320 exposure, 28 frames, no active cooling was used (light was on for short periods only).

Threntepohlia sp. algae

This is really nice. How far is your LED light from your subject?

Thank you. It was about 50-55mm far.

Very encouraging.

Another test.

Same setup with this light at 50mm distance from the specimen, 30 stack frames, light was on for about four seconds during each exposure. Temperature of specimen (piece of moss) increased by about 15-17ºC

Wow, temperature rises that much? is it because of light or because of heat emitted by 35W LED? Can you use a flash?

Yes, 35W LED with collimator lens projects significant amount of infrared radiation onto the specimen. That's why I'm going to experiment with heat mirror.

Theoretically, I can use flash, but for certain applications (shooting outdoor in really bad lighting conditions) I need continuous light. And no, currently I can't use central control of shutter and light because my camera is a piece of crap - it doesn't have any remote option (currently, I'm thinking about Olympus Air).

Several fresh examples of photos taken with this light:

Tortula truncata moss

Plagiomnium insigne moss

Plagiomnium insigne moss, perigonium

Photos were taken both indoor and outdoor in diffused mode (without add-on lens)
