LED tech­nol­o­gy for high­ly ef­fi­cient BLUE light ra­di­a­tion for flu­o­res­cence photg­ra­phy

Keldan's pro­pri­e­tary LED ar­ray tech­nol­o­gy pro­vides a high ef­fi­cien­cy BLUE ra­di­a­tion with 450nm wave­length. This light is de­signed to be used for un­der­wa­ter flu­o­res­cence pho­tog­ra­phy . A unique fea­ture is the vari­able pow­er with 5 sett­in­gs rang­ing from 25-95 Watt.

Soft 80° beam

The light has a very soft and speck­le free beam of 80° in wa­ter (110° im air).

Self-con­tained

The self con­tained de­sign makes this light very easy to use. There is no need for spe­cial mount­ings for the bat­tery can­is­ter.
The in­clud­ed brack­et al­lows easy mount­ing on stan­dard arm sys­tems like the Ul­tra Light arms.

Small and lightweight

The de­sign is op­ti­mized for very small di­men­sions and light weight. You do not find any other light for flu­o­res­cence on the mar­ket which is as small and pow­er­full than the LU­NA 4 BLUE.
The com­plete set (light, brack­et, dif­fus­er) ads on­ly 0.7kg (0.22kg in wa­ter) to your gear.

Tough De­sign

The LED can not break and has al­most un­limit­ed life­time.
Thanks to its overtem­per­a­ture pro­tec­tion, the light can al­so be used out­side the wa­ter.

Li-Ion Bat­tery

The LU­NA 4 BLUE us­es a recharge­able Li-Ion bat­tery­pack which of­fers much high­er pow­er den­si­ty and less weight com­pared to NiMH bat­teries. The Li-Ion bat­tery­pack al­so of­fers bet­ter per­for­mance in cold wa­ter con­di­tions than NiMH bat­teries do. The bat­tery­pack can be eas­i­ly exchanged within a few se­conds.
The wall adapter ac­cepts 110V to 240V AC. Exchange­able adapter plugs al­low world­wide use.

Charge Dis­play

An eight stage charge lev­el in­di­ca­tor gives you the charge lev­el while charg­ing or div­ing.
