Hey Legacy,
Wait about 6 months and take the pics again.
No power dissipation (heat sinks) or temp control on the LEDs.
They will fade/degrade.
You wasted your money.
You can't mount a high power LED on an FR4 PC board with no temp compensation or ability to dissipate heat without adversely affecting the LED.
You will exceed the junction temps of the device over time and the LED's performance will degrade.
Keep your halogens. You will want to use them again when you LEDs aren't putting out enough light to light to read by in a few months.
Paying $40.00 once is far cheaper than paying $16 three times.
Good Luck
