DAWL DAWL OrcaTorch D620 Canister Light

arkivju – Diver TestsDAWL tal-għaddas OrcaTorch D620 Canister Light

NOT TOO MANY YEARS AGO, I purchased a German state-of-the-art umbilical dive torch.
Kien fih tubu ta’ ħruġ ta’ gass ta’ intensità għolja (HID), li kien jagħti dak li dak iż-żmien kien iddikjarat li kien l-ogħla output ta’ dawl fis-suq u, b’bank kbir ta’ batteriji tal-idrur tal-metall tan-nikil (ni-mh), kien jiftaħar “ whopping” burntime ta’ 60 minuta.
I can remember cringing when I parted with just under a grand for this torch, but it served me well for more than a few seasons of deep, dark technical diving.
Alas, today this monster of a torch is gathering dust in my workshop. Why? Because that 60-minute burntime and 300 lumens of light it delivers is so yesterday.
Today we can enjoy torches with smaller battery-packs providing long-lasting power to LED light-heads that deliver lumens stretching to four or five figures.
UK distributor Sea & Sea sent me a torch to put through the DIVER Test treadmill that on paper would leave my old HID model floundering in the dark.

Id-Disinn
In today’s vernacular, the D620 is called a canister light. In days gone by it would have been referred to as an umbilical light, because it has a separate battery container connected to the light-head by 45cm of waterproof electrical cable.
Id-D620 huwa mħaddem b'erba' batteriji tal-jone tal-liju 18650 rikarikabbli li jinsabu f'canister tal-aluminju tal-grad tal-ajruplani ta '113 x 54mm b'finitura reżistenti għall-korrużjoni tal-ilma baħar anodizzat iebes ta' grad djamant.
Its screw-down head is sealed with twin O-rings to provide a depth-rating of 150m. The battery canister has a built-in slot for belt attachment.
The lamp-head is built from the same hard-coated aluminium alloy. It is 83 x 50mm in diameter and houses a single Cree XHP70 LED nestled in a polished aluminium-alloy reflector. This sits behind an optically coated 4mm-thick disc of toughened glass.
A single switch operates the torch, with 90° rotation needed to unlock it and single pushes to turn it on and scroll through its three power levels. The lamp-head is supplied with an adjustable, rotary Goodman handle, built from the same spec of alloy as used throughout the rest of the torch.
Choices of orange or grey silicon shock-rings are provided with the lamp-head to add some impact resistance. The D620 comes in a PVC carry-case with cut-out foam inserts to house the supplied light, Goodman handle, battery-charger with both mains 240v and car 12v adapters, a wrist lanyard and spare O-rings.
Ir-riflettur tal-liga illustrat jipprovdi raġġ li għandu qalba ċentrali qawwija ta '14 ° bi profil periferali ta' 78 ° aktar artab. Il-Cree LED wieħed jagħti massimu ta '2700 lumens ta' dawl abjad f'intensità ta '16870cd fuq distanza massima ta' 260m (fuq l-art). F'dan l-issettjar huwa ddikjarat li għandu ħin ta 'ħruq ta' 2.5hr.
Settings ulterjuri jipprovdu 800 lumens (medju) b'ħin ta 'ħruq korrispondenti ta' 8hr 50min, u 37hr enormi fl-issettjar l-aktar baxx ta '150 lumens.

Fl-Użu
L-ewwel ħaġa li jolqotni kienet il-kwalità eċċellenti tal-bini ta 'dan id-dawl magħmul fiċ-Ċina; il-kostruzzjoni robusta tagħha u l-finitura anodizzata sabiħa dehret li tnixxi l-klassi.
Wara li ċċarġja l-batteriji bis-sħiħ, ħadt l-OrcaTorch D620 sa Wraysbury Dive Center għall-inizzjali tagħha taħt l-ilma.
Liebes ingwanti niexfa fisser li l-manku Goodman kien jeħtieġ li jiġi aġġustat biex jippermetti l-massa żejda. Dan kien faċli biex tagħmel, iżda kien jeħtieġ wrench Allen biex jinħall il-viti li ma jissaddadx biex tiżdied il-wisa '.
The handle’s depth can be increased or decreased using three pre-set cut-outs, and is locked in place by tightening a stainless thumb-screw. The handle can also be rotated through 90° for ease of storage, and to provide protection to the glass lens when travelling.
The battery-pack was threaded onto the BC waist-belt, and we were ready to go. The Goodman handle positions the light-head steadily and securely on the back of either hand (depending on the user’s preference) but the fingers and thumb remain free to perform tasks such as purging regulators or dumping gas from the BC.
Il-manku aġġustabbli jista 'jitneħħa wkoll, jekk dawl li jinżamm fl-idejn huwa ħaġa tiegħek.
Is-swiċċ tad-dawl kien aċċessibbli ħafna u faċli biex jintuża. Imbotta waħda tixgħelha fl-ogħla produzzjoni tagħha, u pushes qosra sussegwenti tiskrollja mill-issettjar tal-qawwa li fadal ta 'medja, baxxa u mitfija.
Din is-sekwenza issettjata minn qabel malajr saret dwejjaq, peress li kelli nitfi d-dawl qabel ma mmur minn outputs baxxi għal għoljin.
Dawra ta '90° tissakkar is-swiċċ għall-ivvjaġġar jew biex twaqqaf il-bidla aċċidentali taħt l-ilma, u dan il-kompitu kien faċli biex jitwettaq taħt l-ilma, anke f'ingwanti niexfa.
Ir-raġġ kien mifrux fuq angolu wiesa ', bil-hotspot ċentrali strett tiegħu jaqta' l-ilma bħal sikkina sħuna mill-butir.
Fl-ogħla produzzjoni tiegħu, deher li kieku jdub il-blat - 2700 lumens huwa oerhört qawwi, possibilment qawwi wisq għall-użu normali, iżda hemm l-għażla ta 'żewġ livelli ta' dawl aktar baxxi minn fejn tagħżel.
Ippreferi l-issettjar tan-nofs f'800 lumens, li ma ddawwalx ix-xena bħallikieku kien Stamford Bridge fil-lejl tal-partita, u f'viżibilità mnaqqsa ma tatx l-impressjoni li ssuq bil-lejl b'raġġ sħiħ fiċ-ċpar.
Kellha wkoll il-vantaġġ li żżid sostanzjalment il-ħajja tal-batterija li kien fadal.
F'għaddasi sussegwenti ppruvajt pożizzjonijiet ta 'immuntar differenti.
I secured the canister onto the BC’s tank camband strap, and also placed it in a pocket with the zipper closed until only the connecting wire protruded.
It-tnejn urew li kienu għażliet tajbin, iżda l-favorit tiegħi kien li npoġġiha qrib il-ġenbejn, imwaħħla maċ-ċinturin tal-qadd.

konklużjoni
This style of dive-light may not be for everyone – indeed, with dive-torches getting smaller and smaller, they can nearly all be easily positioned on the back of the hand using neoprene sheaths and mounting plates instead of bulky Goodman handles.
I like the solid feel of the Goodman system, and am also a big fan of canister (umbilical) lights. The batteries needed to power these amazingly bright lights are still a bit bulky, but by placing them in a separate container the light-head can remain compact yet pack a punch, with unheard-of outputs and burntimes being achieved.
Meta nqabbel dan id-dawl tad-dive LED modern D620 mal-mudell Ġermaniż antik tiegħi HID taż-żokra bit-tubu enormi tal-batterija tiegħu u l-output top-end darba fuq darba, infakkar kemm il-juggernaut tat-teknoloġija ħafifa mexa 'l bogħod. quddiem fi żmien daqshekk qasir. Huwa simili li tqabbel id-dawl tax-xemgħa mad-dawl tax-xemx.
