It's terrible. It flashes between colors like it wants to give you a seizure. If it had been a slow fade or a solid light that just randomly changed when you turned on the water, ok. But this is spastic.  In the dark it's like washing your hands under a strobe light. Plus the water flow is AWFUL...not a steady flow but thin blasts of water. I can't turn my faucet on full or it will blast the sink and splatter everywhere. Just avoid.

Wow!  This is very bright!  I truly needed a very bright fixture because I have a 29 gallon "high" aquarium, and the light from normal units seldom reaches the bottom plants, because there's more water to pass through.  When I turned this one on, I could hardly believe it; it's brighter than TWO florescent fixtures.  I've not yet been able to determine how plants will grow, because I just began using it, however, the description says it's the right spectrum.

1 month later:
I am getting a sever "Hair Algae" on everything.  I did research, and it seems that LED lights for aquariums have a tendency to produce Hair Algae.  Further research suggests that a hydrogen peroxide treatment to the plants, using a spray bottle, and a well-diluted potion of hydrogen peroxide and water will kill the hair algae, and most other algae also.  For the best results, drain 90% of the waster out of the tank, into one or more buckets.  With the potion READY, spray all the plants with the potion and wait a few seconds, the put the original water back into the tank.  But you have to do so, in such a way, so as to not allow the temperature of the original water to decrease more than 1 or 2 degrees.
The dilution is: 3 mililiters (ml) of the 3% hydrogen peroxide to 1 gallon of water (using the original water).
Next, use the LED in addition to a regular light fixture, so that you do not use the LED for more than a couple hours per day.

Well, I spent $95 on this light fixture...that causes problems; I needed more light than my two previous fixtures could provide, and so I bought this one.  Now...I have to reduce the usage?  I've heard of light diffusers, and maybe I'll try that.

I originally gave this item 5 stars, but now I give it 3.  I don't like spending money on something that I have to use conservatively....

Bench tested today. Some of the best 3mm LEDs I've ever bought

I didn't buy it here, but in ebay and got it in white. I used it for my PC as an accent lighting. Plug in any USB port TV or computer. It came in 20 different colors and the colors are accurate. 5 different brightness and different burst speed from slow glow to seizure flashing speed. Length is about long as a 24 inches computer monitor go from left to right horizontally. Good thing you can add more LED but you need a connector too.

Installed and tested this unit with LED bulbs, although not advertised as LED capable. The LED bulbs work great and will save much power over the life of operation. When first installed, I could not get TEST mode to operate as documented in the product manual. Called support and they said the documented Test mode procedure is incorrect and not to use it. The correct procedure for test mode is to power the unit on and wait until it goes through its initialization, which takes about three minutes; you'll see the scanning led's operating is an indication of the ready state. To enter test mode, rotate the TIME adjustment to 5 SECS and the SUN/MOON adjustment to full SUN/MOON operation, which means the photocell is disabled and the unit will operate all day and all night. Now you can walk the perimeter and stop each time the light switches on then off in 5 seconds. Adjust the sensitivity to the size field of sensor operation for your area. Raise or lower the sensor assembly to also control where the sensing takes place. The procedure on page 15 of the installation manual is helpful for this. Once the adjustments are complete, return the SUN/MOON adjustment back to somewhere closer to the SUN position and the TIME to what you want the light to stay on when sensing movement. This takes the unit out of TEST mode and is setup for normal sensing operation. There is no need to power the unit off for normal operation. I set my adjustments for Time, SUN/MOON, and SENS to mid-range, which provides good operation for my installation.

I was sent one of these to review, and since I have a bunch of 18650 batteries - and lights to go with them - I thought it would make a great addition to my ever growing LED light collection.

It's a sleek, modern looking light that's exceptionally bright, thanks to the battery and the newest generation Cree LED.  The tail switch controls three brightness settings, plus the typical annoying flash and SOS.  The inner lens ring even glows in the dark.

The downside - this thing gets hot. After just four minutes, it was too hot to touch - 112 degrees. So this is not for long term use - maybe a couple of minutes at a time on high, or for longer use, set it on low.  This is due to the compact design, no heat dissipation and very bright CREE T6 LED.

I bought this and razers rgb mech keyboard.

This corsair felt way better, but better than that is corsair SDK and key lighting app. It's extremely full featured allowing complex animations and reactions to key presses, plus allows for alt/shift/ctrl mods allowing visualizing key commands so easy to program.

Plus, several (and increasingly more) games natively support custom lighting. For example, in D3, all keys glow dull red besides the keys set to your actions. Actions with cooldowns are also visualized. Several events in game trigger amazing animations too. In D3 when you level up the whole keyboard blinks and flashes just like the on- screen events.  It's simply amazing and I'm so excited to see more games natively support the sdk.

My son loves things that light up and glow. I am always on the lookout for items that we can play with together to experience the world around us.

I recieved 2 of the LED light up armband in red. It also came with four extra lithium 3 volt batteries. To activate the LED lights in the package you just need to pull out the tab and push the button.

Pushing the button on these armbands gives you three different lighting effects: fast strobing lights, slower blinking lights, & a steady light. I have found the activation button very easy to use. The armband is approximately 10 inches from end to end when fully open but when closed with the velcro it goes to about eight and a half inches to 9 inches.

When these are on I don't feel weighed down or lopsided. They are very comfortable to wear. I was excited to find out that they already had the batteries included and were kind enough to include extra batteries because that can sometimes make or break an item, not having the batteries. I recently received a LED necklace to be used as a nighttime dog collar for my larger dog and was able to combine these two arm bands into one necklace for my 6 pound Chihuahua. I feel like this added versatility has increased the value of this product 10 fold for me. My small dog is a chewer and would have eaten through the LED Rubberlike necklace that I got for my larger dog but because these are nylon he reacts to it as if he is wearing a regular collar.

My son likes to wear these in dark rooms and given the luminosity of the LED lights he does not need another light on in the room. He likes to wear them at different light patterns which I find really funny.

I received this item at a discount in return for my honest and unbiased review of these led armbands. Receipt of this discount has in no way influenced my review of this product. My reviews are based on my experience with the LED armband, I have not been paid for my review.

The Streamlight ProTac HL USB features ten tap programming allowing for the choice of three programs: 1) high/strobe/low 2) high only 3) low/high. First of all whatever you do, do not shine this light into a mirror or onto a white sheet of paper and look at it while the light is on high, because you will be blinded.  I wanted this flashlight because we only have one functioning flashlight in our house.  We live in a wooded area and we find ourselves without electricity more than most people.  We have a lot of trees hanging over the electrical lines, squirrels that try to get warm on the transformers in the winter, its a myriad of reasons so we often find ourselves without electricity for several hours. Therefore, we always need a flashlight. With that said, I had no idea what I had received.  It is without a doubt the most awesome flashlight I have ever owned.  It looks like something a Navy Seal or police officer would carry and probably does.  I was struck first of all by the size.  It is only about six inches long.  I thought, Good grief, what a tiny flashlight, but holy cow the light is out of this world.  It will brighten up an entire room on high.  Even on low, it is amazing the amount of light this thing puts out.  I was getting ready to read the instructions and due to over age 40 eyes and the fact that the instructions are printed in the tiniest print known to man, I used the flashlight to shine on the instructions so I could read them and ended up with a huge black spot before my eyes for a solid minute.  This thing reminds me of the song blinded by the light because that is what it will do.  If anyone ever breaks into your house, simply shine the light into their eyes and you will have time to run or knock them out of the way.  Then I saw the instructions, CAUTION: LED RADIATION-Do not stare into the beam.  When I began reading about programming it, it took me a while to figure out the difference between tapping versus clicking to change the program on the flashlight.  After many attempts and re-reading of the instructions several times with a different flashlight, I figured out that tapping is merely pushing the button not to the point of a full click. I wanted it to be on low.  I don't know why you need it to strobe.  It makes me want to go into a seizure.  Im sure the men out there understand the need for the strobe. I asked my husband but he wasn't sure either.  Maybe if you have a flat tire at night and you want to draw attention to your broken down car, I could see using it for that reason.  Anyhow, you can charge it with the charger they provided or use the USB cord and plug into your computer.  It also comes with a carry case and an adapter to charge it in your vehicle.  I love this flashlight.  I won't have to worry now when we don't have any electricity about lighting candles or lanterns, just turn this on and leave it and you have a fully illuminated room. But, it does get hot and it even has HOT written on the end, but it the instructions say it won't burn you.  The picture attached is in a dark bedroom, shades drawn, door closed, lights out and it is very bright in there.

I bought all three colors.  Red, gold, and blue.  The only thing not represented well was the color of the blue one.  The photo depicts a powder blue color when in fact it is dark blue.  The red is true and the gold looks elegant.  I thought it didn't work when I first got it but it was a matter of holding the button down several seconds rather than a quick punch of the button.  If you want it to come on at it's brightest level just hold the button down several seconds with it on bright and it will turn off while on bright.  Then when you go to turn it back on it will come on again on bright mode simply by holding the button in several seconds once again.  You get used to this very quickly and it is no problem at all.  A lot of these tiny lights don't have the button to turn the light on with.  Instead you twist the head of the thing to turn it on.  I don't like those.  I love the button which is right where your thumb is.  Perfect.

Cool looking stream of LEDs.  The intensity is based of how much work the charger is doing.  When something is completely charged the LEDs stop and turn off.

So cool looking I want to get another to charge my phones in my truck.

This thing is bright!
Easy to use - there is one button. Brice it once for super-nova brightness, twice for end of the world brightness and three times for the gentler burn your retina brightness. This is indeed a very powerful light. It has a built in hook, you can hang it - it lights a good sized area, but don't look into the lighting element. It really does hurt!

Can also be run from 4 D batteries, it also comes with a rather short USB cable to charge the unit, or put in the other way to charge your device from the unit. It does not come with a USB C cable for newer devices, but you can plug a USB C cable in .

Good, bright and useful.

Looks cool and works well - I wish I could set it on one color rather than pulsing between 3 colors.

The switch does what it is supposed to do.  It has timer settings for each time.  However, I have three complaints that prevent me from buying more to replace all the fan switches in my house and from granting a four- or five-star review.

1. The blue LEDs are BRIGHT!  They are brighter than the nightlight in my girls' bathroom.  There doesn't appear to be any way to calm down the brightness.  For this reason alone I am considering returning the two switches that I bought.

2. They are not intuitive to use.  One would think that one would press the button for the amount of time you'd like the timer to count down.  You want the device to turn off in five minutes?  Press the 5-min button.  Wrong.  You do press the button for the time you want (which turns on the super-bright blue LED next to the button, confirming your press), but you then have to press the large button at the bottom to turn the device on.  Also, there is a super-bright blue LED light next to the large button.  When the device is off, the super-bright blue LED next to this button is on.  When the device is in countdown mode, the super-bright blue LED is OFF.  The logic is backwards, and if the switch is controlling an unseen/unheard device, the user would assume they were controlling it incorrectly.

3. Finally, because of the way the large button at the bottom is used, there is no simple bypass on/off mode. You HAVE to use a timer. In many instances, this is probably just fine, but if you have an application where you might want to occasionally override the timer, this is not your switch.

If I had designed the switch, I would have used much less bright LEDs, and I would likely have selected a green color.  I would have designed the switch to enter countdown mode as soon as you pressed the time you wanted.  I would have designed the big button at the bottom to be a simple on/off switch with no timer.  And I would have reversed the logic of the LED on the big switch so that the LED would be lit when the circuit was active, and off when the circuit was off.

Innovative product that is a cinch to set up. Just plug it in and it begins working! Easy in and out if you want to remove the light to use as a flashlight. The motion sensitivity is accurate.

How I use it: I get up before dawn on work days and take our Weimaraner dog out. That means taking her down two flights of stairs that are pitch dark. There is a light switch at the head of the stairs, but the dog is so eager to get outside that she races down the stairs before I can get to the light switch. Multiple times she has gone head over heels down the dark stairs, so the Ivation light is a great solution. She races past the light, and it turns on, lighting the stairs so she can safely navigate them.

Why not 5 stars you ask? Well, I'd like to see the following improvements:

-- The ability to dim the light. It's quite bright and I'd not describe it as a night light. It's more of a beacon. Those LEDs emit a very sharp and cool (not warm) color.

--- The ability to dial up and down the amount of time the light stays on once triggered by the motion detector. It's locked in to 20 seconds, and I find that a bit too long for my use. It seems like it would be an easy fix to enable 5 second increments, between 5 and 30 seconds. I'd choose 10 or 15 seconds.

I agree the blue light is way too bright.
I moved it to the rear of the machine to keep it from blinding me and it still draws my attention when it flashes.
Super fast transfer speed though so it is worth putting up with.
