Glo-Toob Waterproof Emergency Dive Light

I dislike most of the bike lights on the market. Their shapes are cumbersome to carry around (to prevent from getting stolen) but you can only use them while riding your bike. They tend to be over priced and $20 range lights are cheaply made. Small ones use flat 3V batteries that are expensive (unless bought online). Others use multiple AAA batteries and that make them too big.For a long while, my solution was Nite Ize SpotLit Red. It was designed for dogs and sort of worked as a bike blinker. The problems is it gobbles up flat 3V batteries fast and I had to stock pile the batteries. It also emits light mostly on one side so often the light was not very visible when the light gets flipped.I finally fed up and did an extensive search and finally found my near perfect bike tail blinker- Glo-Toob AAA.For the past two weeks, Glo-Toob stays on my keychain that clips with a carabiner on my jeans’ belt loop while I ride bicycle.As an added bonus, Glo-Toob is also great as an ultralight camping / emergency lantern. As an LED lantern (although they don’t advertise as one) this is the smallest/lightest I could find. The amber color is a nice replacement for a candle lantern. It doesn’t give off any heat but physiologically it almost feels like a growing heat element placed inside of an ice tube. With my very unscientific comparison using a charged Eneloop rechargeable AAA battery, the high (100% brightness) mode is twice or three times brighter than a Ikea tea light and the low (25% brightness) is about the same brightness as the tea light.The light distribution pattern is far more useful than a tea light candle lantern that emits light above but cast a big shadow below. Glo-Toob AAA emits light sides and downwards and very little above. This is great when you hang this somewhere above your head. Also since this casts very little shadow below, you can place this directly on your book or map to read.Also a great marker that helps you to make it back to your tent from bathroom trips.Pro:- Uses single AAA battery.- with rechargeable AAA battery you don’t need to buy battery for this for a long time.- lights 360 degree- bright (as a maker light)- Really Water proof (200ft)- warm amber color- just about enough modes without over complication (high, low, blink)- easy and fast to cycle through three different modes- plastic parts are thick and appear to be durable- easy to attach to anything with a carabiner or lanyard- attaches to a keychain thus no need to worry about getting your bicycle blinker stolen- multiple usage (bike blinker, lantern, marker, emergency search and rescue, EDC, diving)Con:- Blinking mode is too fast.- A tad too big as a keychain light.- Doesn’t really doubles as a regular flashlight (but works in a pinch)- They don’t state what kind of plastic this is made of so the durability is unknown.- The battery life spec is not very long for current LED standard.- More orange color than amber.

My friend is a sea diver and uses these for his dives. After seeing him use them in rough ocean use, I decided to grab one myself to replace my glowsticks that I use to be seen. I usually always carry some form of light to mark my location and be seen by friends. From hiking in the dark, climbing at night, cycling or marking the tree that I have climbed up to set up my hunting perch...you can always find a glowstick or LED fingerlight that I have left behind for people to spot.The problem was waste, these glowsticks need to be recycled or thrown away...the LED lights use lithium button batteries...Enter the Glo-Toob.Powered by a single, easy to find, easy to replace AAA battery with an amazing 15 hour battery life. It's bright, durable, water proof and shock proof. What more can you want from a rugged marker light? I attach this to my backpack when I cycle at night and I can be seen from long distances, I use it when I snowboard at night with the lanyard around my neck, I tie it to my tree when I am hunting, I attach it to my dog's collar when we go on night walks and I even used it at Burning Man to be seen in complete darkness.

I purchased two of these lights (a white and a blue) to use as tank marker lights for scuba diving for my buddy and me. Note: lights are negatively buoyant and don't float above your tank. Otherwise, they worked well.EXCEPT my light fell apart after about 5 dives. The electronic portion fell out of the clear tube casing and is now polluting the sea somewhere. Over a week ago I tried to contact Glo-Toob customer support, and have yet to hear from them. This is unacceptable in many respects. Very disappointed, I definitely WOULD NOT BUY again.

I have the light on the backpack I wear while riding my motorcycle, and it does seem to keep some vehicles at a respectful distance. Maybe it's the bright police blue? LOL. The battery drains a bit fast, however, so I dinged it one star for that reason.

Update:I've used the same Glo-toob on my dog for the past 7 years. We've taken it on many walks, dog park visits, and even on camping trips. The light is still working perfectly.Original Review:I bought this to replace the Nite Ize SpotLit clip-on light I used to have on my dog's collar. The Nite Ize light worked fine for night time walks but could not stand up to my husky mix's rough play at the dog park. After just one or two trips to the dog park, the Nite Ize was broken. So I spent the extra money for a Glo-Toob light and I am pleased I did. Several trips to the dog park and plenty of rough play later and the Glo-Toob is still good as new. Even on the 25% power setting, is also much brighter than my previous light was and lets me easily spot my dog no matter what dark corner of the dog park she's at. It even lights up our path a little when we go on night time walks. And since it's waterproof, I don't have to worry about water or dirt getting inside and causing damage (my dog likes to splash water and roll around in dirt). I'm sure the light will hold up great during camping trips too.I was a little concerned that my dog (about 45 lbs) would be hurt or at least bothered by the solid tube when it swings around as she runs, plays, and shakes herself off. But she doesn't seem to notice it in the least.It's also very convenient that I can use my rechargeable AAA batteries so I don't have to worry about the light running out of juice and not having a fresh battery on hand. (Much fewer batteries to throw away too, which is a plus!)
