About Underwater Kinetics Sunlight C4 eLED Dive Light

The C4 eLED waterproof light is Underwater Kinetics lightest weight primary light. It is designed to fit smaller hands while still offering brightness comparable to lights twice its size. Its water-cooled heat sink actually increases brightness underwater and improves burn time. For maximum illumination and a comfortable fit, the C4 is the perfect solution. Unlike the standard glass envelope lamps used since Edison, the LED will not break when dropped. The life expectancy is well over 5,000 hours.

The light emitted by the LED (light emitting diode) is similar to sunlight and travels farther underwater than the more yellow light from an Edison lamp. In addition a power control circuit is built into the light to help maintain the same brightness throughout the discharge of a set of batteries. A tough O-ring sealed ABS and polycarbonate case protects the components all the way down to 500' (152.4 meters). The small size of the C4 eLED makes it ideal for revealing the incredible marine life hidden under ledges.

The C4 eLED is powered by 4 disposable C"-cell alkaline batteries (included), or if you wish to upgrade it with a rechargeable kit the SKU: UKTRKC4E is available eliminating the need for replacement power cells. With alkaline batteries the light has a burn time of 8 hours on the high power setting and 8 hours on low. The C4 eLED Dive Lights dual 5-Watt LED's produces 275 lumens of brightness on high power and 190 lumens on low. The lights beam distance is 330' (100 meters) on high-mode and 305' (93 meters) on low-mode. The light measures 6.8" x 5.6" x 3.2" (17.27 x 14.22 x 8.13 cm) and weighs 25oz (708.74g).

No better light for freediving

This review comes from a freediver. This is the last light I will own. It's small, but powerful. And it isn't too much of a weight to carry down to 20m and back. The batteries last for 4-6 hours of use, and the lights will never need replacing. Oh yeah, and the bulbs (there are two) fire up right away - no waiting 15 seconds like the HID bulbs. No better dive light for freedivers.

Great light.


Made in USA


Awesome light, worth the investment


Great light for night dives. Strong, concentrated light beam. Turns on and stays on. A bit heavy and takes a bit of getting used to (particularly if you are petite) but thus far has been worth the investment. I have not had it long enough to assess bulb life or battery drain.


Very good light


It´s very bright and compact for your money.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
Gena B  You can't beat these reviews! I am excited to try this light for myself!
DAVID A  I was given this light as a gift from my wife and it ROCKED. I was leery about its large size, but during night dives with Blackbeards cruises, it really made a huge difference. I am buying one for my son to replace his puny dive light.
MICHAEL B  6 years old and still going strong.
TARA B  A great light. Lightweight and powerful.
TODD K  works great
DAVID S  Great light. Heavy with batteries; be careful that your luggage doesn't go overweight.
PHILIP P  Very nice light. Lightweight, compact and a large bright beam with two power settings. There are certainly brighter lights out there, most are bulkier and heavier but for what this offers, it is very nice.
NICHOLAS M  Smallish light with lots of light and batteries seem to last a long time. Like that on and off switch can be locked to prevent accidential turning on.
AMIRIS A  one of the brightest torches out there and compact enough to hold "C" bateries ( instead of the bulky/heavier "D" batts.)
Shopper  is this the newest version of this light?From kinetics website part number 19052 for the black C4 eLED (L1)
Marilyn S  It is this the newest version of this light. C4 eLED (L1)
JOSEPH T  Worked fine until I lost it underwater chasing a lobster.
STEPHEN L  I can't say for sure if it is the newest one or not since I have had it for a couple of years. I can say that it is a very good and powerful light and extremely good for night diving.
AMIRIS A  I believe so. Very compact, light, and bright
KIRBY M  No, if you to Underwater Kinetics web site they have newer models but this web site have given you this information not another customer.
JEFF W  I don't know if its the latest ......however....this is a great all around light....primary or secondary uses...long battery life
Shopper  Is the lumens on this lamp 205 or 337?
KEITH P  I have the old style which is 205.
TARA B  The lumens on this light are 275 on high 190 on low. It is a really powerful but lightweight dive light.
