This unmatched LED was custom-built based on ReefLedLab’s design and is solely manufactured on our order, using the most efficient crystals existing at the time of manufacture. An official reference by Semileds provides the parameters for crystals used in the manufacturing of this LED.
TSLC states that by maintaining an LED crystal temperature of less than 75C, one can use the LED at a current greater than 700ma as is described in the technical document for the basic option of the LED. Since the LED is installed on MCPCB with the SinkPADTM technology using a heat sink with passive cooling, it is possible to use it up to 700ma. Also, our research shows that when using active cooling of the LED heat sink, if the crystal temperature is kept less than 75C, it can function up to 1A.
We do not recommend using the crystals at currents above 700ma without checking the crystal temperature using thermal vision or a pyrometer.
Semileds informs that radiation power must be multiplied by 18-20% for the package factor. The radiation power of our LED, depending on the supply current, is given in the table below:
|Current, ma||Radiation, mW (@ 25оС)||Voltage drop, V|
Thus, the real quantity of radiation received from one LED is up to 5800mWt, it is 10-20 times more than the cheap single-crystal violet LED's that are commonplace on the market.
NOTE: This LED produces a large quantity of short wavelength radiation which can be very dangerous for your eyesight! It is forbidden to look at the LED radiation from a short distance or in the darkness.
