LED Module  TWstrip
  TWstrip is a 12" length strip module being soldered with 12 pieces high power LED lamps, which are grouped in two separate strings.  One string of six LED lamps is of 2700K CCT, and the other string of six LED lamps is of 6500K CCT.  By adjusting individually the light intensities of those two LED strings, desired color temperature can then be achieved.  
Multiple pieces of TWstrip can be connected together and in parallel to one constant voltage LED driver.  In order to avoid thermal runaway happened, the LED driver IC regulates the current flowing in each LED string at a specified value, like 700mA.  If without the current regulating circuitry, the LED string having the lowest forward voltage (Vf) will draw the most current and end up with a premature failure.
TWstrip can be driven in 4 selections of current, namely, 200mA, 350mA, 500mA, and 700mA. The four-position rotary switch built on the TWstrip helps select the desired current flowing in each LED string.  Furthermore the current setting can be done on site if desired.
