Giant light bulb!
At best, this light bulb is not very eco-friendly. I’d go so far as to call it eco-hostile. If you’re going to use a light bulb this freakishly large, the least you can do is use one of those corkscrew-shaped ones. That would save, like, a bazillion BTUs or something. But let’s be honest – even at that, anybody who needs a light bulb this large needs to reassess their energy usage levels.
