A unique mechanical design aspires to remove heat from this LED light bulb’s insides, but you still need to keep external ventilation in mind.

With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.
