Dual Head Clip on LED Desk Light, 3 Modes, 5-Level Dimmer, Flexible for Dorm Room, Computer, Piano, Kids

This light was perfect to add light to my racks of sewing thread. Matching colors is sometimes very important and the amount of light available is the difference in selecting the right color. Since it was so light weight I was able to hang the light from a nail between the racks and can bend and move each one to get the light to shine where I need it most. It’s very bright, versatile, and easy to use. A great value for the money and seems sturdy enough to last.

I needed a light to illuminate the keyboard and work surface of my computer desk without casting glib on the dual screens. This light works perfectly for that application. It mounted to the shelf supporting my monitors. This puts the lamp heads above the work surface and below the monitor screens. The lamp heads rotate so I can position them to avoid light on the screens or in my eyes. The light is on 9 to 10 hours on a typical day. The LEDs provide great light with no heat. I would happily recommend this light to someone who would be using them in a similar situation.

General: Each of the two lamp heads has 13 “cool” and 7 “warm” LEDs. The “Switch” button (top on the control switch) turns the lamps on -- initially in the “cool light” mode (13 LEDs x 2 on), then switches to the “warm light” mode (7 LEDs x 2 on), then to what the manufacturer describes as the “natural light” mode (20 LEDs x 2 on.) The LEDs are powered by a cord that terminates with a USB plug that can be fed directly from a USB socket or plugged into a provided USB to 110v power adapter. In addition to the three different color mode choices provided by the Switch button, the “Dimming” button (center on the control switch) provides five different brightness settings (20%, 40%, 60%, 80%, and 100%.) The manufacturer states that this light produces 330 lumens. I have no way of measuring the light output. However, in the “natural light” mode (i.e., all LEDs on -- both the cool and the warm) at the 100% brightness settings, it provides a decent (but not great) amount of light for reading over a small desktop area (about 24” x 18”) if the lamp heads are no more than about 12” above the surface. I’m not clear why a light of this type needs a “Timing” function (bottom button on the control switch) but that may appeal to some people. This button selects between 3 hours, 6 hours, and 12 hours. Pros: The spring clamp is sturdy and the goose neck tubes are sufficiently stiff to hold the lamp heads in position. (However, I’m not sure how well the tubes would hold up to being adjusted multiple times each day, like an architect’s desk light.) Cons: 1) It is not possible to turn this light on using a remote-switched 110v socket (either a manually controlled socket or a “smart” socket controlled by an Alexa/Echo or a similar device. 2) The lamp lacks a “one-press” on/off button. The manufacturer states that this light has a “memory” function which “will automatically resume the BRIGHTNESS SETTING [emphasis added] of the previous use when restarted.” This statement is correct, but only as far as it goes. After the light is turned off by using the Switch button (by cycling through the “cool,” “warm,” and “natural” modes to off), when it is then turned back on again -- while the brightness setting is the same as when it was turned off -- the light color mode always is “cool,” requiring one or two additional button presses to get to “warm” or to “natural.” More problematic, however, is that when line power is cut to the light and then restored (such as by a remote control socket) pressing the Switch button turns the light on but NOT at the last selected brightness level. The default starting setting from a line power off/on cycle (after pressing the Switch button once) is the “cool” light mode at 60% brightness. In other words, to go from off to the “natural light” mode (all LEDs on) at 100% brightness after a line power off/on cycle takes five button presses: Three of the Switch button (to go from off to “cool,” to “warm,” to “natural”) and then two more presses of the Dimming button (to go from 60% to 80% to 100% brightness.) That’s a lot of button presses. I believe that the manufacturer should modify the memory feature of this light so that it will remember both the brightness setting and the color mode that was last set and come on directly --without any button presses -- after a line power off/on cycle. If that modification is too difficult, then I recommend that the Timing button be replaced with a simple “one-press” on/off button that won’t require repeated cycling through color modes every time the light is used. Conclusion: This light appears to be suitable primarily for accent lighting and for small area (as opposed to focused task) illumination that only needs a modest number of lumens. The options for color and brightness provide flexibility. It probably would make a good light for a piano, a bookcase, or a display table. UPDATED REVIEW 12/18/2018 After my initial review was posted, I was contacted by DZLight via Amazon offering a refund or a replacement with another one of their lights that would work with a smart socket. I very much appreciate this excellent customer service. However, I wouldn’t feel right requesting a refund since the light I received isn’t defective in anyway, it just has some limitations that I described in my initial review. DZLight explained that, because the switch on this light is, itself, smart, it won’t work with smart sockets. I wasn’t previously aware of this limitation concerning smart switches. I suspect (but have no hard evidence) that similar lights by other manufacturers using smart switches would also not work well with smart sockets. Although I still wouldn’t recommend this light as a general purpose desk light (I just don’t believe that 330 lumens is bright enough), I’ve found that it makes an very fine computer keyboard light. I’ve fastened the two lamp tubes together end-to-end and now have about 18 inches of narrow beam focused light positioned about six inches above my keyboard. Before fastening the tubes together, I searched Amazon for an equivalent LED keyboard light. The closest I could find were “grand piano lights” that start about 10 times the cost of this light. For that price difference, I can more than live with the multiple switch button presses. I thank DZLight for their responsiveness to my concerns. I’ve adjusted my rating to four stars.

I love it so much I bought a second set. My wife uses them all the time. The clip on it is strong and holds well. It came with a usb power plug to use it with an outlet. I use it with my usb battery bank so I can take it out to the car and garage. Works great as a work light. The only complaint she has with them is that its kinda hard to adjust them to stay out of your eyes. And when she does get right, there in my eyes. Needs some type of visor or clip on shade. But overall. Still a great light.

I’ve been using this light for the past month with no problems. I have it clipped onto the top of one of my monitors but with each light spread out in opposite directions. It provides plenty of light for video conferencing as well as being able to see my keyboard. Love the different lighting and brightness options which allows me to switch levels throughout the day as needed (the brightest light option is just too bright for me). Would definitely buy again.

I have had this light for just about a year. It was only used from January - March - then again from Nov until now (March 2021). I have it clipped onto the top of my monitor shining down on my desktop. As a teacher, it provides light on my desk if I need the lights turned off in the room. Its overall functionality is good. It serves its purpose. The arms could be stronger as you cannot adjust them often or they don't stay in place. Getting them adjusted in the position you want them is a bit of a challenge, but once you get it there, leave it and don't touch it. We were all remote from March - November. I had unplugged this unit when we went remote but left it attached to my monitor. When I returned 9 months later and plugged this in, I noticed that it doesn't power off anymore. there are LEDs that are "yellow" and do not shut down unless I unplug the USB. This is a bit of an inconvenience and would have been 4 stars if it wasn't for this issue.

Purchased the light to help with properly lighting a green screen while streaming. It works well and has several brightness settings which are handy for other lighting needs. The materials seem to be of mid-quality that will last if not abused or handled too much. The arms can have their position adjusted and have held their position well so far. A good value for the price.

Received product and installed behind my triple monitor setup to be used as a desk light and as an accent/behind webcam light (webcam on order), but initial impressions for at least the brightness and controls are satisfactory. The light seems sturdy and the flexible arms retains its memory enough for my intensions. I'll update review after using the product extensively, but so far, good product and I would recommend.
