About

His­to­ry

KEL­DAN start­ed in the ear­ly 90s when Daniel Keller man­u­fac­tured a dive light as a birth­day pre­sent to his wife. The per­for­mance and qual­i­ty of the light was so good that he was asked to pro­duced more for mem­bers of his lo­cal dive club. Since then, the busi­ness has grown to a world­wide re­spect­ed man­u­fac­tur­er of high­est per­form­ing un­der­wa­ter video light­ing equip­ments.

Re­search and De­vel­op­ment

KEL­DAN is conti­nous­ly work­ing on the im­prove­ment of our prod­uct line. We care­ful­ly de­sign all our op­ti­cal, me­chan­i­cal and elec­tron­ic com­po­nents in-house to make sure even the pro­fes­sio­n­als will be im­pressed by the qual­i­ty of the prod­ucts.
All of the op­ti­cal spe­c­i­fi­ca­tions are care­ful­ly eval­u­at­ed and ver­i­fied in our own lab. As a re­sult, we are able to make ul­tra com­pact lights that are not on­ly ex­treme­ly bright but of­fer the best beam and col­ors for spe­cial­ty ap­pli­ca­tions such as un­der­wa­ter videos.

Our Prod­ucts

KEL­DAN video lights are known for very com­pact size, low weight and ex­cel­lent pho­to­met­ric spe­c­i­fi­ca­tions. Thanks to it mo­d­u­lar de­sign, our lights can be con­fig­ured to sat­is­fy all needs of pro­fes­sio­n­al un­der­wa­ter video work. With our prod­ucts we set the stan­dard for high end un­der­wa­ter video light­ing.

KEL­DAN hand­held lights are full fea­tured dive lights which are op­ti­mized for max­i­mum bright­ness, small size and us­er friend­ly­ness. KEL­DAN lights are lead­ing edge prod­ucts with un­matched func­tio­n­al­i­ty and per­for­mance. With our dif­fer­ent mod­els we cov­er all ap­pli­ca­tions start­ing from very com­pact lights for easy trav­el­ing up to ex­treme­ly bright lights for pro­fes­sio­n­al ap­pli­ca­tions.

Our Cus­tomers

KEL­DAN video lights are used by de­mand­ing video­g­ra­phers for se­mi pro­fes­sio­n­al vide­o­work and by pro­fes­sio­n­als work­ing for na­ture TV chan­nels like Na­tio­n­al Ge­o­graph­ic or for the movie in­dus­try.

KEL­DAN hand­held lights are used by divers who need a light which is de­signed for high­est per­for­mance, re­li­a­bil­i­ty and han­dling com­fort. Typ­i­cal ap­pli­ca­tion are div­ing in lakes, night dives, ice- wreck- and tech­ni­cal div­ing, res­cue and out­door op­er­a­tions and law en­force­ment. We sup­p­ly pro­fes­sio­n­al cus­tomers like Ja­pa­nese Self De­fense Forces, Swiss Po­lice , Nor­we­gian NAVY and many others.

The Per­son be­hind KEL­DAN

Daniel Keller re­ceived his MSc in elec­tri­cal en­gi­neer­ing in 1988 from the Swiss Fed­er­al In­sti­tute of Tech­nol­o­gy in Zurich (ETHZ).
He worked for many years in the semi­con­duc­tor in­dus­try as in­te­grat­ed cir­cuit de­sign­er. Be­side his en­gage­ment for KEL­DAN, he is al­so in­volved in a swiss start­up com­pany in the med­i­cal in­dus­try.
