Flower-like lamp with pentagon shaped petals. Lasercut with aluminium foil reflector/heatspreader.

Tested for 3 hours with a 1 watt LED (at 350 mA), in 24 deg Celsius ambient temperature. The temperature of cardboard just behind the LED reached 45 degrees, and the LED module 60 degrees - both fine.

WARNING: Using a 3 watt LED is untested, and may be unsafe.
