"Ours is rather flat on the top, but I realize the shape is bound to vary with each item, so not much can be done about that."

"I received my first salt lamp from my daughter as a Christmas gift."
"wasn't broken or smashed to bits like some other lamps - it's much bigger than others I have purchased."
"Also, the light is more red than pink and does not produce enough light to replace a traditional lamp for those curious."
"At first I loved this salt lamp and even bought more as gifts but then after I had it about 4 - 5 weeks the dimmer switch quit working and so now it doesn't work and hasn't since last September/October 2017."
"This salt lamp was incredibly light in color, which resulted in a bright light rather than a soft glow."

I was a little worried after hearing about the salt lamp fires and subsequent recalls, so I really appreciated this company distancing its products from those right in the description."

"One of the best salt lamps I’ve ever purchased!!!"

"Bright, powerful, burns holes in things."
"Great Laser, powerful, so far reliable."
"When I opened it I was surprised at the build quality, I guess I was expecting a cheap thrown together knock off but got the complete opposite. When you focus this laser down to a pinpoint it is really amazing to see almost anything you point it at burst into flames or spew smoke as throw it were being boiled in a sense. I can't wait to order the larger more powerful unit here in a few weeks to start ethching aluminum with the flatbed cnc x/y table and get away from the deaktop engraver for plastics and wood."
"Im so glad I bought this for a project because this is totally the type of thing I would impulse buy to mess around with lasers."
"2 inches long [not including fan] and 1.2 inches tall this laser module is small - tested and it works fine - does not seem to heat up too quickly and it does burn things quickly - eye damage via reflected beam is almost instantaneous so a set of laser goggles are advisable - has threaded holes in the base for mounting - the power supply is a standard 12 volt 2.5 amp switching supply - good price would recommend.."
"This will not do anything to white plastic, but will burn dark plastic, wood and paper."
"Wow!"

"Many intelligent features here: The clip has a 'foot' that adapts to thicker/thinner surfaces, gripping with enough friction to hold without crushing."
"I really do like this light, as each light operates independently, and has two levels of brightness."
"My only complaint is it takes longer to charge it then the amount of time you can use it before it starts getting dull and pretty much useless."
"This has 2 settings, one of which is moderately bright, and the other is super bright making it easy for me to read in pitch black conditions."
"This double headed version I ordered to use for my music stand, and I am mildly disappointed with the intensity of the light."
"Seriously excellent and BRIGHT."
"Best book light I've ever purchased, it's def a live saver when I have to catch up on some reading late at night while everyone else is sleeping."

"These are opto isolators for assuring that noisy inputs from an ancillary unit whose input is required, don't mess with the circuits in the box."
"I use them on arduinos to trigger other circuits and avoid an electrical connection between them."
"Just what I was looking for; now my project has a better design and better digital line protection and coupling."
"Work fine and good price."
"Nice, inexpensive selection of Opto-Isolators."

Best Optoelectronic Displays
Our high CRI (Color Rendering Index) means that the LED is emitting more of the color spectrum than a typical LED. Most states will not allow electricians or home owners to install LED lighting products that have not been tested by a certification laboratory. The UL CERTIFICATION is indication of a superior quality product that has passed numerous tests before getting its approval. Improving energy efficiency can reduce emissions that contribute to global warming, mercury contamination in lakes, acid rain, and nuclear waste.

"It doesn't bother us, but if we turn the switch of when these bulbs are on a low setting, then they don't turn on again unless we move the dimmer."
"When I installed the lights at first, I had one flickering light and one dim light so I was uncertain and declined to review these lights."
"Most but not all are on dimming GE Z Wave dimmers so they are used daily due to automatic schedule."
"We got these for our old recessed canister lights in the kitchen but they wouldn't fit ... the neck of the bulb near the socket was too wide and so the bulbs wouldn't screw into the socket (the problem wasn't the light, but my old fixtures, because we tried similar LED makes and they wouldn't fit either)."
"These are so bright that I couldn't tell they were dimming."
"Color is a nice bright white - not yellow, not blue, just clean white."
"Replaced the old bulbs with these today and have to say the difference is really night and day."
