I am a huge fan of white LEDs. Light Emitting Diodes are bright, compact, and require little power, which makes them perfect for small spaces. While reorganizing my utility closet last winter, I became frustrated that it did not have any built-in source of light. Briefly contemplating the idea of rewiring of my house, I decided to look for a battery powered light source made to stick to a wall or ceiling.

While browsing through Amazon’s listings of LED lights, I noticed Sylvania’s Dot-it light. The design was so sleek and different from the other lights on the market that I immediately got out my credit card and put it in my shopping basket.

Initial impressions

The Sylvania Dot-it is a small battery powered LED light that can placed virtually anywhere that needs illumination. Using a 3M 300LSE reusable adhesive, the light can stick to a variety of non-conventional surfaces such as fabric, leather or glass as well as plaster and wood. This type of adhesive is also suitable for a wide variety of temperatures.

Measuring a little over 2.5 inches in diameter and .8 inches in height, the Dot-it contains a cluster of 3 LEDs. Each LED is rated at 10,000-12,000 mcd (mcd, or millicandela, is a common measurement of luminous intensity in LEDs) with a viewing angle of 15 degrees.

The Dot-it is simply packaged in cardboard-backed plastic. This is one of my favorite types of packaging because it’s easy to open and leaves behind minimal waste.

Although the Dot-it is available in a variety of fanciful colors, I selected the boring, yet safe, natural aluminum color so that it matches my home decor.

Product Testing

I’ve been testing the Sylvania Dot-it light for about 3 months, specifically on the inside wall of my utility closet. Since I don’t frequently use this space, I thought a multi-month testing period was important to fully test the features and durability of this light.

The Dot-it light has a good feel to it. The outside casing appears to made of metal and has a smooth finish. All the seams fit well and do not creak.

The back is made of a grey plastic and is held together by three philips head screws. This is also where the 3M adhesive is located.

The included two AAA batteries are already in place behind the Dot-it’s back panel, so there’s no need to use a screwdriver until the batteries need to be replaced. Since LED lights draw such a small amount of power, I expect that it will be a long time until they require a fresh set.

Similar to the DaysAgo timers I previously reviewed, there is pull-out tab that “activates” the included AAA batteries so that no power is wasted while in transit.

The acrylic dome that houses the LEDs is also a toggle switch for the light. To turn the light on, simply tap the center dome. The motion on the dome is very smooth and clicks quietly when activated. The dome is made of a plastic that is not scratch-proof, but resists the type of small scratches that can occur from light use.

The 3M 300LSE adhesive sticks very well to my wall. It is removable and re-stickable, which is important since the Dot-it must be detached to replace the batteries. In the past three months I have noticed no drifting or change in it’s position on my wall. If you need to replace the adhesive, there are several 3rd party websites that sell 3M 300LSE to consumers.

The one thing I was severely disappointed with about this product is its solitary function: furnishing light. Three LEDs do not provide nearly enough light for my intended purpose, a 4×3 utility closet. My Dot-it only illuminates the space with the brightness of a night-light. This is helpful for getting a general idea of the closet’s contents, but not enough light to be useful.

To distract myself from discomfiture, I sat down for a little math. I understand that arithmetic makes for less than riveting reading, so feel free to skip to the last sentence of the next paragraph– you won’t be missing much.

Using the luminous intensity numbers provided to me by Sylvania, I decided to calculate the brightness of my light in layman’s terms. Each LED is rated at 10-12 thousand mcd. Taking the average, 11,000 mcd, I multiplied it by the three LEDs in the light which totals about 33,000 mcd. Sounds like a lot, but raw numbers are meaningless without relative comparison. The average candle is 1,000 mcd and the average 100 Watt incandescent light bulb provides 120,000 mcd. So, a rough estimate of the amount of light given off my the Dot-it is similar to 33 candles or a 25 Watt bulb which is consistent with my observations.

Although I like the concept and design of the Dot-it LED Light, the light is far too dim for my original purpose. However, the versatile adhesive makes it useful in applications with textured surfaces that require little light, like illuminating the inside of a toolbox or suitcase. I believe that the Dot-it could be significantly improved by adding more or brighter LEDs to the light dome.

  2. 3 LEDs is pretty much useless. On the other hand, I have a 21 LED flashlight (bought from an Amazon Marketplace vendor) that actually works quite well.

    In a nutshell, I agree. The number of LEDs needs to be significantly upped to make this light useful.

  4. I agree with the comments. I’ve tried these lights and LED lights as a booklight. Neither provided sufficient light. One of the problems with LED lights of any strength that I’ve seen is that the light is very focused. It doesn’t spread out to cover a large area like you would need in a closet, drawer or to read a book.

  5. The question is,how do I detach the back of the Sylvania Dot-It to replace the batteries? The light isn’t much good inside a closet if the batteries are dead,right?
    Please let me know.

  6. Battery Replacement

    I just swapped the batteries in one.

    1. Rip it off the wall.
    2. Remove the 3 small screws in the back.
    3. Smack it on the table until the back comes off. Do NOT try to pry it off, as the back is a circle that does not extend all the way to the sides. (This is the non-obvious step IMHO.)
    4. Swap batteries (3 AAA).
    5. Replace screws; there are 6 holes-use the 3 that are recessed a bit.

    1. I thought Dot it was a good idea when I bought it. I want to replace the batteries. So I remove the tiny itsy bitsy screws and try and twist the back off as shown on the back card. No go. I smacked the thing hard fifty times or more on the table as suggested but the back does not come off. Now I am ready to throw the bloody thing against the wall and make sure it shatters into a million pieces. Problem is I have now thrown it off my 2nd floor balcony and the thing still won’t come apart!!!!!

    2. I hit it on the table, nothing happened. Then I took the very tip of a paring knife, put it in the hole a screw came out of, leverage and the back pops right off!

  7. The screws were readily removed with a steak knife. I pri
    ed the light off the wall first of course. The back was very easily removed. Batteries replaced, and light reinstalled. All under 10 Minutes.

  8. I have 3 of the Dot-it’s which I love. However cannot get the back off to change batteries. Guess they will be trashed. Will not purchase again!
