I checked out the price on the L1070-66-60 LED sold by Marubeni that Swakandakari mentioned in his post. The cost for 1 to 9 units is $347.14 each. Heat sinks are $17.36 eqch for 1 to 9 units and lenses are $40.50, so one LED and accessories would cost around $400.00. When I heard that, I changed my plans. Instead of trying to make a helmet or headset as the patent shows, I decided to make a stationary lamp type device such as artman mentioned in his post. Assuming that a single LED would be sufficient, the total cost would probably be less than $500. I’ve already spent that on a pulsed biomagnetic device (recently ordered) so it doesn’t seem excessive. My concern, as an electronics ignoramus, is doing something that would blow out the LED and force me to spend another $350.00. Can anyone offer advice on the voltage, current, etc. that these LEDs require? It can't be as simple as just hooking it up to household current.
