hi guys,
 
What are your opinions on these lights?
Are they worth the money?
And how much better is the 600 over the 500?
And what other lights in there price range do you recomend?
 
Also whats the going rate for these two lights second hand?
 
cheers
ryan

(imho) a waste of time because of the halogen lamps.  The 700 is a 150 discharge unit but even then I think they're a bit dim for any serious use.
 
No idea on prices I'm afraid.

hi norty,
 
The lights will be used for part of a mobile dj rig doing rave themed night and that sort of thing.
I dont really want to spend more than £300 a light.
Also i cant make my mind up weather to go for moving heads or scanners. i like how smooth and controlded the moving heads are but to get a reasonably desent one you could gewt two scanners that do the same thing. but scanners just seem to be so quick and edjey (spelling).
 
any help would be great thanks

Also i have been looking at the isolution irock scanners. what are your opinions on these. they do a 150watt discharge version, but how would this compare in brightness to say a 250watt halogen?

Generally the rule of thumb is discharge sources are 3-4 times brighter than halogen per watt - ie 150w discharge will = 450 - 600w of halogen. this of course assumes high quality clean optics, with the lamp correctly alighned.
 
scans can move as smoothly as moving heads, its all in the programming of the control. For mobile disco use, i would stick with moving mirrors unless you have loads of money
 
For £300 a head, you could find some serious kit like clay paky miniscan hpe's which would knock the sh*t out of everything this side of a martin 918

hi csg, thanks for the help.
i had been looking at discharge lamps for a while now but could only seem to find 150watt dischage lights in my price range so i was woried that they wernt going to be bright enough. but now i now they compare to 3-4 times brighter than a halogen im much more happy to pay for a discharge.
 
i supose scanners would be more suted to mobile use but i just love the look of moving heads! ow well i will just have to wait till im a bit older and have a bit more money and maybe get some better moving heads then.
 
wheres the best place to look for clay paky lights ect.?
 
cheers

take a look on ebay for the miniscans - they come up quite regularly and seem to sell for approx £600 a pair
note that they come in several versions - miniscan hpe's are the ones you want - they are 300w discharge, and cost a couple of grand each new...

our club have many martin scx units of varying sizes. dont bother, poorly made, poor optics, poor resolution (smoothness) of mirror movements and as said, mostly halogen which is pants.
 
just for your info on discharge lamps, halogen has fragile filiments which are inefficient, break easily in transit, and burn out quickly. Discharge lamps instead have 2 'stumps' which have seriously high voltages through, causing electrical arc'ing, and once heated up, a bright white light source rather than the yellowy halogen glow. think household floodlight compared to footy stadium floodlights. same kinda thing, obviously on completely different ends of the scale however.

I would say that in my experience, 150w of discharge source comes nowhere near 3 to 4 times the brightness of halogen.  When comparing 250w of halogen to 150w of discharge I'd say at a push it might be a bit brighter, but a lot of that is down to the colour temp.  That said, not all 250 halogens are created equal either.  ELC3 and ELC5 are longer life and so dimmer.  Some of my M33 lamped units are very bright even for halogens.

Perhaps - but remember that at the 150w end of the scale, budgets are usually tight and optics lossy

also, the elc is a complete optical unit complete with a very carefully alighed reflector, which will not be the case with an hti-150. Ill look up the lumen / watt figures when i have a moment, but there is no doubt that discharge lamps are far more efficient than halogen
 
ok, quartz halogen = 24 lumen / watt
metal halide discharge = 100 lumen / watt
 
so, slightly over 1:4  ratio!

ok well it seems that the feedback for the martin scanners asnt good so i definatly wont be going for them. and it seems that going for a discharge lamp is a must!
 
Are there any other options apart from Clay Paky miniscan?

Robe Clubscan 250CT are getting cheaper all the time.  Around £200-£250 each with 250w MSD250/2 lamp.  The older DJ scan 250XT are cheaper but rarer as now out of production.  150XT is still being made as far as I'm aware but 'only' 150w.  imho, if you're going to get some scans, get 250w or higher. You can always dim them if too bright.
 
Martin 518 are a reasonable light but very slow by todays standards.
