A couple of ideas:
1. Can you move the Spot Light further away? (never mind, saw the bottom of your post stating you can't...)
2. Try covering with plastic bags to shade down the light. Since it's LED they don't produce a lot of heat.
3. The new Spirit LEDs have a strobe and Short Circuit function that could ease the light output and give an effect.
You can try making a dimmer switch like icepick suggested, but some LEDs are not dimmable. If you do use a dimmer, make sure you buy one...
