Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Good for use in daytime also, looking in nooks for sea life, a must have, I carry it with me on all dive. Good back-up for a night dive but would not use as a main light.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

This is a very compact light. I use it both for dives and outside as well. The light is intense and battery life is very long. It easily fits into the BC pocket. I have another one with LEDs but I prefer the SL4 because it is brighter.

This is a great light to have in your BC as a backup or also a great primary light

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Having owned and/or used several dive lights during my 23 years of diving I can attest to the superiority of the Underwater Kinetics products. They are very durable and well built having experienced only one malfunction (wouldn't shut off) with one product EVER. Even though I had owned this SL4 unit for nine years, UK made things right with NO hassle. They really stand behind their products... you can't ask for anything better than that kind of customer service. I will NEVER buy anything other than UK products.

Awesome light for the money. Bright, focused beam, compact, and well designed. Awesome value, and a great backup light!

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

I keep the light in my BC pocket and it is a great light for low light situations and night dives.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

I had one of these since 1996 and took it on 100+ dives. I finally dropped something heavy on it and broke it. Luckily they still make it.

Great flashlight and the best warranty. UK stands behind their product even years after purchase.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

It is very bright! I love the compact design.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

a great back up light.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Used it for night diving and peeking into crevices during the day. This is a great light for the price, but I like my PC Lite a little better. It is sometimes difficult to load batteries into the UK SL4 because they get stuck at an angle. Also, my IkeLite beam pattern is a little more even and brighter. Still, great for [$], and a very good backup light.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

this is a good light for checking out dark crevises or even a night dive, good battery life, my first one leaked and i sent it back to leisure pro and they sent me a new one, i would buy another or recomend it to another diver.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Great focused beam to look under ledges and in small crevices. Awesome light. Last one I had did begin to leak but it must have been something I did as my buddy has had his almost 10 years now with no issues. He is more careful with his gear than I am . Have used light to 150 feet.

carried as a backup light - also used by my students

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Small, powerful light! I keep it in my BC pocket at all times. Great for lighting up crevices in daytime and powerful enough to be used as a main light at night!

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Great small light. Easily fits in your BC pocket or if you attach a clip, you can clip it on a D-ring on your BC. Either way, it is compact and gives good light. I have a SL6 as well but it is awkward to put in the BC pockets and is cumbersom clipped on the outside of the BC. Overall I far prefer the SL4 for its smaller, more compact size.

Good back-up for the price.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

If this one is like my UK Mini Q40, I'm going to love it. I didn't mark any of the pros besides size as I've only put it to use 3x. It is heavy and large for what I'm accustomed to (the Q40 is rather tiny), but it is much smaller and lighter than the average person's main dive light. Using it on a night dive in Monterey as my main dive light, it was perfect! And I always remove the batteries after using it, to prolong the life of the batteries.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Easy to use, very compact, precise beam.
Can be used as a primary, but better suited as a backup.
Also very useful when reef diving to see what's under there.
Very pleased with the purchase, especially at that price.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

The size was just right for my use. Also good for snorking at night. Purchased one for my dive buddy he also recommended it.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Fits in pocket, and provides good light

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

I have used this light for night dives and cavern dives. The beam of light it produces is very intense, but it may be too narrow for some purposes. Overall is works great. It fits in my BC pockets and it is easy to handle. Battery life is great as well.

Takes a beating [...]

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Night or twilight dives in the ocean often have enough natural light that the large lights can spoil your night vision. This one puts a small, powerful spot on objects requiring further observation. The narrow beam does not create the halo of particles around it like a wide beam light. Might not be as good if it is REAL dark.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

I have used this light in fresh water and saltwater and have never had a problem. I own two of these and have recommended them to others.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

I would highly recommend this light as a backup or primary. It is light, rugged, dependable and has a very strong focused beam that penetrates deep into holes and caves. My only con is that the replacement bulbs if needed are too expensive to carry a spare. You might as well replace the light when the bulb goes. Having said this the only time I have needed to is when I left the light on after a dive and it overheated

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

This is a great light. My first one did have the lens crack, but that was probably from use and abuse.

Comments about Underwater Kinetics Underwater Kinetics Sunlight SL4 Dive Light:

Used when inside of a wreck. Very strong light for the size around 120 lumens. The SL6 is bigger and will not fit into most pockets and the light output to me is not worth the bulk and weight. SL4 is my light of choice.
