Re: FIRST Fundraiser: Selling LED "Lightbulbs"

The documentation provided by FIRST somewhat deceptively states "replaces up to a conventional 60-watt household light bulb". Here is the complete announcement -- http://www.usfirst.org/roboticsprogr....aspx?id=18445

Even the manufacturers data declares "Replacement for 60W incandescent bulb", see the T-67004S on this link from the FIRST resource page -- http://webbuilder2.asiannet.com/ftp/2253/tess-DM.pdf3

As mentioned earlier, by the lumen rating, these bulbs are very close to 40W of equivalent output. The last thing we need are lots of dissatisfied customers who paid $20 for something they were led to believe (by the published documentation) should perform like 60W bulbs. We need to be careful that FIRST does not get a bad name from this campaign.

An article from The Telegraph states: "Crucially, the EU legislation requires manufacturers to make only scientifically based claims for their lights. An energy-efficient bulb, for example, that claims to be the equivalent of a 60W tungsten bulb must have a minimum light output of 806 luminous flux"
