NTHU installs over 200 OLED candle-light lamps at Taiwan's Smangus tribe

Taiwan's National Tsing-Hua University (NTHU) Professor Jou has been researching the hazards of blue light for many years, warning us against the hazards of modern lighting and focusing on OLED lighting as the technology that enables low blue-light emission lighting. In 2015, NTHU started to develop its low blue-light candle-light orange-type OLED technology, initially in collaboration with Wisechip and later with China-based OLED lighting producer First-o-lite.

NTHU has been promoting these candle-light OLEDs for the Smangus tribe in Taiwan's Jianshi Township which has been avoiding artificial light pollution. NTHU and the tribe managed to raise money to produce 240 OLED lamps, 90 for street lights and the rest to light up more than 100 cabins in the tribe's village. This is a beautiful project and hopefully will bring more attention to the hazards of blue light and the advantages of OLED lighting technologies.

In December 2018, First-o-lite, together with NTHU, launched the first candle-light OLED desk lamp. We posted a review of this OLED lamp in April 2019. First-o-lite apparently has a capacity to produce around 30,000 such panels each month. The retail price is $199 - although First-o-lite told us that it does not intend to sell it directly to consumers but only offer it to business partners and distributors.

NTHU researchers say that white LED is linked to breast cancer, may case irreversible eye damage, suppresses melatonin secretion at night and is linked to all sorts of health problems - and is even found to attract flying insects. It turns out that inorganic-LEDs emit over 3 times more blue light than OLEDs.
