Since most common power supplies are (nearly) constant-voltage sources, LED fixtures must include a power converter, or at least a current-limiting resistor. In some applications, the internal resistance of small batteries is sufficient to keep current within the LED rating.

The LED's depends on its material. Ohm's law and Kirchhoff's circuit laws are used to calculate the appropriate resistor value, by subtracting the LED's from the supply voltage and dividing by the desired operating current. With a sufficiently high supply voltage, multiple LEDs in series can be powered with one resistor.
Maplin Electronic Supplies was established in 1972 as a mail order business by Roger Allen, Sandra Allen and Doug Simmons. The company started in a bedroom at the Allens' home in Rayleigh, Essex, after the two electronics enthusiasts were disappointed by the complexity and poor availability of existing electronic component suppliers.
Most basic supplies in the '80s were a fraction of the cost today. The cost of gas was just $1.12 — less than half of today's prices. ... The store was unique at the time because it offered ...
