That is a heck of a deal. 2 – 150W equivalent CFL’s for a dollar!
If I found those I would buy a bunch, each bulb is 2600 lumen. CFL’s are on ther way out, but you can’t beat the lumen to dollar ratio here. 5200 lumen for a buck, are you kidding me? For certain applications this is a great buy.
Just a couple of years ago, I ordered 4 - 150W equivalent CFL’s in daylight color from Amazon. I remember I paid $8.98 each. It killed me to do it, but I NEEDED them.
The ones you found are warm white, actually better for most other applications.
When I say I’d buy a bunch, what I mean is I would “invest” $10 and get 10 packs. That would be 20 bulbs. I would put them aside and probably one day I would use some. If not, (not likely) I have only wasted $10. Don’t forget, I already spent $36 on just 4 of these.
