Normally 6 to 12 vdc bulbs have been used in the robots brain assembly. This has been working fine, but there are a few issues with doing that. Heat being the biggest, as some of us have plastic brains they are subject to melting if the lamps generate too much heat. To make matters worse, the clear bubble just traps the heat in. Also, when a bulb burns out, it is quite difficult to disassemble the head to gain access to the brain for repair. This LED board set is made up of 3 PCBs with 32 high intensity LEDs. These lamp types generate very little heat, and do no burn out anywhere near as fast as a typical lamp would. Plus they draw less current, and that means longer battery life.
