I saw a post on Facebook the other day.... someone had found a rechargeable Ott Light at Costco!! I didn't think too much about it until I registered for the Jingle Bell Crop this morning... with a full charge, the lamp will work for 3 hours on battery power. Not a full crop, but better than no lamp at all!
And the best part???
Here's a photo I found online (not at Costco.ca).... only difference is mine is black.
It's charging now.... will let you know what I think of it after it's charged.
I already use an Ott Light just like this only plugged into the wall all the time.... can't recommend the Ott Lights enough!
