Banned LED bulbs Report from Dec 14, 2011 With the new energy conservation requirements, incandescent bulbs be phased out, increasing interest in alternative lighting. The lamps which the National Electrical Safety Board has looked at are (therefore) the incandescent bulb replacement LED bulbs. They are based on modern LED technology and all the lamps tested contains a small power pack, situated in the lamp socket. The Safety Board has recently given a variety of (these) LED lamps sales ban. The most common reason is electrical grid disturbances, but they also interfere with radio frequencies.Comment Overall, it should also be noted that lab tested specifications, as agreed among the manufacturers, rarely conform with real life usage. [A problem of course familiar to fluorescent bulb users too – as with the long unnatural 3 hour on-off cycle lifespan testing, given that many bulbs are switched on and off for short periods… which happens to markedly reduce CFL life, and again, the loss of brightness that also effectively reduces their life] The problems with LED, and the standards applying to them is also covered on http://ceolas.net/#li15ledax and onwards, with some safety issues covered on http://ceolas.net/#li20ledax. From an American angle, an interesting court case against false LED advertising: From the Federal Trade Commission press release, 2010:
The lights disrupted other electrical products. Only one in five LED lamps passed the test without comment.European survey In parallel with the National Electrical Safety Board’s market surveillance of LED lights, the EU carried out an investigation. The EU surveillance is not strictly comparable to the Safety Boards’s market surveillance, but shows similar shortcomings. The results also show that manufacturers who use LED technology are very poor at complying with the Directive: The reason for this is that LED technology is so new and there have appeared many new manufacturers in the market that are simply not aware of the directive, said Ulf Johansson at the Safety Board. Clearer rules One of several measures aimed at improving the situation is that the European Commission gives the European Committee for Standardisation mandate to supplement and clarify standards in the field. The aim is to help traders in the market to more easily use the current rules. Continued control The National Electrical Safety Board will, in line with other market surveillance authorities in the EU, check the LEDs in 2012 as well. It also plans to follow up on last year’s surveillance with a campaign aimed at improving information about the LED lights.

FTC Shines a Light on Company’s Deceptive Claims for its LED Bulbs Agency Charges Firm With Misrepresenting the Light Output and Life Expectancy of its Bulbs: The Federal Trade Commission has sued a California-based light bulb manufacturer and its principals to stop them from misleading consumers by exaggerating the light output and life expectancy of its Light Emitting Diode (LED) bulbs. As part of the FTC’s continuing work to stop deceptive advertising,the agency filed a complaint charging that since 2008, Lights of America, Inc. has overstated the light output and life expectancy of its LED bulbs on packages and in brochures. The agency also charges that Lights of America misled consumers about how the brightness of its LED bulbs compares to traditional incandescent lights.A 2011 update, pdf document: http://www.ftc.gov/os/caselist/0923145/110330lightsofamericamotion.pdf “Accordingly, the Court should deny the Vakils’ Motion to Dismiss and enter its Tentative Decision as its ruling on this matter….” Meanwhile, in 2012, with the FTC supervised new lighting label regulations, GE has found its own color coding way to give the information:
GE is currently rolling out a series of five new boxes that’ll hit store shelves by summer and, it hopes, change the way Americans do their bulb shopping. The FTC-mandated label will appear (where else?) on the back of the boxes…The color coding is meant to represent “strong, vibrant”, “cozy relaxing” lighting etc
For example, the lowest-power bulb (210 lumens) comes in a lavender box labeled “subtle, reassuring light,” while the higher-power 1,170-lumen bulb’s box is bright green termed as “fresh, energizing light.”Never mind the uneven light spectrum of this kind of lighting, as indeed with CFLs 😉 Light spectrum compared for different lamp types in an earlier blog post here dealing with UV light radiation, some more diagrams in the equivalent post on the Freedom Light Bulb blog.
