I guess my expectations of these lights didn't reflect the reality of what they were....probably my fault for not reading every little detail on these. What I expected: about 1" diameter lights that produced ample enough light, so when they were strung like above a table, one could see what they were doing. Not bright, not something like read, but you could put your glass down and see if it will hit anything. What the lights actually are" about 5/8" diameter lights that are fairly faint. When suspended above a table, it is very difficult to see anything at about 3' distance from the lights.
I find these not very useful are are 100% for decorative purposes. Do not expect these lights to produce enough light to actually see anything.
