lightsource Posted September 18, 2009 Share Posted September 18, 2009 Hi all, Looking at buying some secondhand profiles, but noticed the Strand Cantata (26/44) and others come in a choice of either Axial and Standard. Could anyone give any advice as to the advantages / disadvantages of axial over standard. The BR wiki only helps so far. This is for advice only, and is not specific to a job. Input appreciated.

gareth Posted September 19, 2009 Share Posted September 19, 2009 but noticed the Strand Cantata (26/44) and others come in a choice of either Axial and StandardThe Cantata was never offered in an axial version. The only profile I can think of which was available in a choice of axial or base-down was the CCT Silhouette. 'Standard' is not the right way to describe the opposite of axial, really - it's usually referred to as simply 'base-down'. In fact, in this age of GKV and HPL-lamped profiles, it could be argued that axial lamp mounting *is* in fact 'standard' if such a standard were to actually exist. The term comes from the fact that the filament of the lamp is aligned along the axis of the optical path - hence axial. Base-down, as in Cantatas, Preludes, ADBs, etc. simply denotes that the lamp base sits below the reflector rather than behind it, and the filament sits inside the reflector perpendicular to the optical axis of the unit.

David A Posted September 19, 2009 Share Posted September 19, 2009 Selecon Aclaim Profiles are available in either format, at 240 volt, one could generalize that axials are brighter and base down tend to be more robust but less efficient. Link to comment Share on other sites More sharing options...
richard_cooper Posted September 19, 2009 Share Posted September 19, 2009 The Cantata was never offered in an axial version. The only profile I can think of which was available in a choice of axial or base-down was the CCT Silhouette. Whilst this was my thought too, usedlighting.co.uk seem to have some available. I thought it was a misprint, but if you compare the photos on the profiles page of this and the other cantatas below of the same beam angle, it certainly appears to have a longer lamp housing. Also a google for "Cantata axial" brings up a few hits including This datasheet. Link to comment Share on other sites More sharing options...
paulears Posted September 19, 2009 Share Posted September 19, 2009 'cantata' and 'axial' are on that page, but on different lines - the word axial is attached to SL? Link to comment Share on other sites More sharing options...

I can't see any reference to the SL on either of the linked pages. Link to comment Share on other sites More sharing options...

paulears Posted September 19, 2009 Share Posted September 19, 2009 searching for the word cantata in the document brings back only this20x Strand Cantata Zoom Profile 18/32 1.2kw2x Strand Cantata Zoom Profile 26/44 1.2kw9x Strand SL Axial Zoom Profile 23/50 600w Seems fairly clear? Based on the period Cantatas were in production, the design would seem to preclude an axial version. Some pretty severe modifications of the lamp house would be needed. The only scenario could be if Strand maybe hand-built some axial versions to assess if they would work. As they introduced the SL instead, perhaps we should assume it didn't work? Over the years, lots of weird one-offs have been made by Strand. Maybe the OP has just bumped into another one. From the documents and info I have, they've never sold an axial Cantata, but that doesn't mean they didn't make one? Link to comment Share on other sites More sharing options...

Sorry cheap shot having just having spent time testing and maintaining our SL stock! None of this matters of course, but the usedlighting link claims to have 15 examples...

paulears Posted September 19, 2009 Share Posted September 19, 2009 AHA!American market 120V axial versions - Datasheet here 1000W lamp, similar shape to the more common ones. So a 230V version quite possible as a retrofit? The picture on the used lighting site has different proportions, however - the lamphouse is much longer. The line drawings are the same, as far as I can see to the UK version with 1.2K lamp - so mystery not quite resolved. Link to comment Share on other sites More sharing options...
Ynot Posted September 19, 2009 Share Posted September 19, 2009 AHA!American market 120V axial versions - Datasheet hereYou know, I have a distant memory suggesting that some Optiques I hired a ways back were axial mounted, but the data sheets show them as base-down. Optiques, I thought, were described to me AS the axial version of Cantata.Rather surprised to see this one, however...1000W lamp, similar shape to the more common ones.

RoyJ Posted September 19, 2009 Share Posted September 19, 2009 :blink: As previously stated the selecon acclaims come as either axial or base down, we have the base down condenser version,but one of our local theatres has the axial versions.The axial versions do seem more efficient but do have a weakness in that,when adjusting the peaky/flat adjustment at the back, the lamp blows.This aside,the axials are good,but could work out expensive lamp wise.I wouldn't be without my base down versions.I think its a case of horses for courses really,hope this helps.Ialso have no experiance of a axial cantata.

Don Allen Posted September 20, 2009 Share Posted September 20, 2009 From my experience with the old CCT30 axials, old axials did not work. Maybe they were waiting for the right lamp to come along as the fel lamp used in the CCT30 and an early Selecon profile, their light output was very poor. The Selecon Acclaim axial with its 600 watt lamp has over 4 times the light output of the CCT30, doing a side by side comparison and uses 400 watts less power. As with all fixtures, you need to make sure any lamp adjusting mechanisms are moving freely before powering up the fixture for any adjustments. With the exception of the base down Selecon Pacific, any modern axial should outperform a base down fixture as there is not so large a chunk of reflector missing where the lamp enters the reflector. Off topic, but for information, Strand had two very successful axial floods, the Patt 137 and Patt60http://www.strandarchive.co.uk/lanterns/p60.html Link to comment Share on other sites More sharing options...
