DZLight Dual Head LED Reading Light, DZLight 20W Dimmable Clip on Light with Auto-Off Timer, 3 Lighting Modes 5-Level Dimmer, Flexible Clip on Lamp for Desk, Bedroom, Office, Adapter Included

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 12/18/2018After 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.

When I first took this light out of the box, I thought "cheap". Yes, it feels cheaply built. Lots of plastic, no premium materials. However, it has flexibility that other lights don't have. With two light bars, each on its own flexible arm, you can more accurately aim the light where you need it. I was looking for a LED light to place over my 32" monitor to provide more light for my webcam during meetings, as the light from my large 32" screen reflected on my face to give a blueish cast to the image. I tried other desk or clamp lamps, but couldn't get them to position correctly. I have a shelf over my desk (above my monitor) and I needed a light that I could clamp to the front of the shelf, and bend the arm(s) so the light would face me. With this light, I am able to do that so that both arms are more or less horizontal over the top of the monitor with the light facing me.Controls are not great. There is an inline switch box on the power cord with three buttons. One button cycles from on (all LEDs) to on (warm LEDs) to on (cool LEDs) to off. The middle button cycles the brightness level. The other button cycles between several timer lengths for auto shut-off. There is no memory to recall your previous settings so when you turn it on it always starts with all LED's at full brightness.This does us a USB plug so you can plug it into a USB port on your computer or a USB hub with power, or a USB charger, if you want. It does come with a USB power adapter that you can use if you don't have another USB port handy.I like the flexibility of configurations you can get from this light, but I would feel better if it were constructed of higher quality materials and had more flexible controls.

I purchased this dual head lamp to clip to my bed headboard so I could do some night time reading.Pro: This thing is really bright. It can light up my room on its own. I like the multi color modes instead of just having a bright white option. The buttons are easy to press and the heads are on a flexible extension. I also use it while reading my phone. Because the neck of the lamp is just over my shoulder, there's sometimes a bit of glare. However, that's easily solved by repositioning the lamp heads.Con: I wish this lamp had a longer neck or some way to sit it higher on a table. I would use this as my reading lamp when using my laptop. However, the neck of the lamp just reaches over my laptop monitor. I wish it were a bit longer so the light could be placed higher above the monitor.Would I purchase this again? Yes for a reading lamp that can clamp onto my bed headboard. I really like the flexibility of having two lamp heads. My suggestion is make a version of this with a longer neck or someway to stand it higher up.Enjoy

Needed a light for a large sound mixing board at church. With two heads, it reaches wide enough, and each head is so thin as to not block the view of the controls. Dimmable is an important feature to minimize light pollution, and to customize to each operator's preference. Flex neck and long head gave us the reach we needed, with the adjustability to not shine in anyone's eyes. Grateful to retire the old short gooseneck incandescent desk lamp that never got the job done right.

it worth $30 - no doubt,

One of the lights the goose neck is loose and does not hold the light straight...
