Newegg offers the Collection 6-watt (40-watt Equivalent) A19 LED Light Bulb
, model no. CL-G60E-6W, for $4.99
for shipping. That's $6 under the lowest total price we could find for a 40-watt equivalent A19 LED light bulb, although we saw it for a buck less two weeks ago. (For further comparison, we saw a 6-pack for $25 shipped last week.) It features a purported lifespan of up to 20,000 hours.
