Anyway, I recently purchased 5 of these bulbs from Wal-mart for $5 each. The ones that I bought were to replace my porch/exterior lights, and I think they work perfectly for that. One light stays on 24/7 (mostly because we simply forget or are too lazy to go to the switch) and has been going solid for two months now, but the others are more recent and get switched on and off daily.

They are a "warm white" and I honestly would not know they are LED by the color if I hadn't installed them myself.

We'll see if they last, but compared to the florescent bulbs at 11W each, we could leave them on all day every day and not use as much energy as forgetting to switch the florescent ones off just four times for an entire day. (Not an unusual occurrence for us.) That would still be about 4kWh for the switched ones, but I'd guess we are really closer to 1.5kWh for actual use, 2.5 total, compared to well over 10-20kWh otherwise, saving us $1-2/month.

So if they last 10-20 months, they will produce a positive net savings.
