Because of the price of the bigger OTTLites, I bought a regular light bulb with the curly que and it is OTT. I got it Joanns for about $4 and you can screw it into any regular lamp or floor lamp. I was really surprised that it was an OTT. It says on the bottom that it is made in China, Model 15ED420 and brightness is 900 lumens, light appearance 5850 K, 15 watts energy used. I got it about August of 2016. I would like another one so the next flyer that comes out, I hope they are in there or I can use the coupon. Worth trying out I'd say.
