Product Description

Whether chopping veggies or showcasing a kid's birthday cake, this Sylvania 72421 three-pack of LED under-cabinet lights illuminates to perfection. The round shaped lights project a very bright white, spot-light-type beam of light onto the counter below, offering economical space-specific illumination. No more dark, hidden countertop spaces. Even more, the energy-efficient lights feature a convenient motion-sensor function, which means they turn on automatically when needed and shut off all on their own. Each wireless light requires three AA batteries to operate (batteries included), and they come with magnets and self-adhesive tape for fast, easy installation in minutes. Simply peel, position, and stick (the magnet holds the light to its mounted base). A great house-warming gift idea, these super-handy under-cabinet lights are available in black, white, and silver to coordinate with almost any decor.

These are not bad for a spot type light. The brightness is comparable to luxeon led flashlight. The light color is bright white, not amber, not soft white. The light is bright enough to cause serious damage to your eyes if you look directly into the lit light. Since it is a spotlight your would have to try to look "dead-on" into the light beam for this to happen. These are designed as under cabinet or over countertop use. So, these should be safe as designed.

Now for some little things. These lights get warm during use. I measured the upper surface (mounting) temperature of several lights while operating on BRIGHT. The room temperature was 75 degrees fahrenheit and humidity at 45%. The surface temperature of the lights peaked at 113 degrees fahrenheit in just under 5 minutes. Temperature decreased thereafter and remained constant at about 100 degrees. I continued to monitor temps for 5 more minutes. Temperature did not increase in that time. I believe these lights are safe as designed. No further temps were taken, i felt reasonably satisfied the lights are NOT a fire hazard.

Lights have 3 states, (OFF, ON-Bright, ON-Dim). Lights are switched between these states by passing your hand within 3 to 4 inches across the red windowed sensor next to the light lens. My lights will not switch at any distance greater than 4 inches. This is a good thing. I do not want the light switching on as I reach for a paper towel. Lights auto shut off after 1 hour if you should forget to switch them off manually.

I have no idea how long batteries last. I am not up to wasting batteries for that test. Each light comes with 3 alkaline batteries already installed.

I bought these locally from a wholesale club, but so far so good. First, they're BRIGHT! I can't emphasize this enough. I've seen all sorts of tap-lights and even used some of the newer LED lights. They were all toys compared to this light! There's a warning on the back of the lights not to look directly into them and they're not kidding.

I agree with the previous reviewer's complaint that they produce a very small spotlight beam. BUT, this is very easily fixed. When you take the cover off to change batteries, look at the lens holder. There will be a slot on one side. Just insert a screwdriver into the slot and the entire lens/optic pop right out. In doing so you now have a light which puts out a perfect smooth flood of light. In this configuration it puts out a very similar light level and pattern (albeit much cooler white) as the traditional halogen hockey puck lights. I don't know why Sylvania put the optic in to begin with. This is how they should have shipped.

I have had a set of these lights for about 2 years and can say they are great, no big deals, they work , they turn off and on just like it says. OK, the little stuff:

I had to mount mine under some wood cabinets and since it is a big metal coin like disk they adhere to this would be great on a smooth flat surface but on wood I had to add some Elmer's Glue to make it stay put. Not a big deal a knife and sandpaper will make it all disappear if I ever care to remove it (without the light its almost invisible anyway)

In a real emergency I wish it had a "stay-on" position but each hour you will have to turn it back on, saves batteries but in a power outage it is a minor pain.

Thats about it, they are BRIGHT (do not look directly into them, not safe) and the batteries last about 1 year give or take a month depending on use. That is with the no0-name batteries that come with it, I put some Ray-O-Vac alkaline batteries in them and sorry it is still running great so you get what you pay for in batteries.

Great for the use, I like the "wave your hand" idea to turn them on -off-dim, it is just a nice little thing if your hands are wet/greasy/dirty you do not have to touch them.

Almost forgot I just ordered 11 more sets for me and a couple for relatives so you can be sure I am pleased.

UPDATE JAN 2013: I still have these and they still work exactly as promised, still highly recommend them. The only thing I might mention is to add these to you check list of things once a year to make sure the batteries have not died. The ones that came with it died but I replaced them with Duracall and have never had to replace another one (I should mention that we have a week with no power so they got used a LOT during that time)

These are very solid, they have a good weight to them, unlike other cheap push-lights. They are quite bright, and provide more than adequate illumination for a cabinet, closet, or over a countertop. I actually set them up under my daughter's loft bed. She also takes one up into bed at times when she goes to sleep. The only con is when you pass by and accidentally either turn it on or off but really that isn't a problem,and if it does- just tap it again- problem solved. I am glad I chose these, as I also bought a 2 pack from another online "helpful household products" catalouge and they are terrible. Granted I only paid a few dollars for the set, so no big deal. I'd buy them again.
I will add that they can be operated by tapping as I did in the video- or by swiping in front of them. I put two under the medicine cabinet in the bathroom and they always turn on with just a passing of my hand under the cabinet. They actually reflect alot of light from the white sink as well, making them even brighter. I don't have to wake people up at night when going in the bathroom now as I find the light they give off in there to be most adequate.
