I have an interesting tag that I stole from a lamp in a store. It
claims that an expensive lamp which uses a 60 W halogen bulb is more
efficient and saves money over a conventional 60 W bulb. I compared the
rated lumens and wattage with a conventional light bulb and found they
were comparable. Hmmm I have asked students whether the claim was
true.
