About Tektite 3500XL Expedition 10-Watt LED strobe

Strobe 3500XL Expedition

For many years, Tektite Strobes have been renowned for their performance and ruggedness. The new Strobe 3500XL Expedition now sets the bar beyond any other strobe. Designed for the rigors of commercial and scientific diving use, this strobe has similar brightness to the Strobe 300. The battery housing is computer machined from a solid bar of aircraft aluminum; all new solid-state circuitry and 10 watt LED lamp makes this strobe the MOST RUGGED and shock resistant of any strobe Tektiteb build, or anyone else makes! No fragile glass strobe tubes to break. This double O-ring sealed strobe will run 20 hours on a set of batteries, at a sustained flash rate of +/-60 flashes per minute. It can be seen for miles at night. Use for scientific divers, military and fire fighters.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
BRUCE T  This appeared to be the most rugged strobe I could find. As a USCG licensed master I consider a reliable strobe an absolute essential for any night activity on the water; boating or diving.
Shopper  How does this turn on? Does it have a switch?
JEFFREY M  The top screws down making contact to turn it on. Tighten it down before you enter water. There are two o-rings that the tops slides over. It does not have a button or slide switch.
David C  Does the Tektite 3500XL float?
JEFFREY M  No, it does not float. I don't think any of their strobes float, but this one is very rugged and bright. I have used the regular strobes and the bulb breaks after awhile this LED one is going on two years and going strong.
David C  How do you turn the Tektite 3500XL on (It's not clear in the picture)? Does it have a on/off switch or do you have to twist the end?
