How to gauge LED flicker
A few years ago, back when ordinary LED bulbs still sold for north of $10 a piece, there was a great brouhaha about LED light flicker. Light flicker can certainly be dangerous. Sufficiently intense flicker at between 3 and 70 Hz can cause epileptic seizure in a small percentage of the population. And flicker that […]
LEDs replace single-contact bayonet-base incandescents
LEDtronics announced new additions to its industry-leading offering of HYPERLINK intermediate-based LED bulbs that fit in enclosed fixtures, with low voltage, 160-degree spherical illumination, low power consumption, and high lumen intensity. The B605SM series is available either as a 14VAC/VDC bulb that HYPERLINK replaces incandescent lamps 67, 89, 97, 98, 1095, 1155, and 5008 or […]
