IRW Posted May 25, 2017 Posted May 25, 2017 Hi All,Having recently had a demo of an Elumen8 MP75 LED Fresnel RGBW, I am suitably impressed enough to be considering putting in an order for a small pile of them to replace an ageing set of Strand Prelude PC's in one of our venues. Size-wise, it's pretty comparable to the Prelude, which is one of my specification points for this replacement, and when set up side-by-side, output is also pretty comparable, both in size and intensity, and light-leaks between fixture and barn-doors where minimal, unlike the Chauvet equivalent in the demo video. Obviously it's the usual 'slightly dimmer in open-white, but wins-hands-down-for-saturated-colours' LED jobbie, and the only real down side we noticed was that it uses a 'cool-white' LED for the W. Does anyone have any comment to make on these fixtures? Or can anyone suggest another viable Prelude replacement? Due to the way our Preludes tend to be used, 'small form factor RGBW fresnel' is what we're after for this. Thanks, Ian
paulears Posted May 25, 2017 Posted May 25, 2017 What I don't quite understand is why they are called Fresnels, when they don't have Fresnel lenses? The specs give the same kinds of data as a normal PC lensed unit. These frosted type lenses give a softish light but are more like PCs, not Fresnels. I wish they'd all put some proper light data in the specs. No doubt a useful product, but for five hundred quid you could get a moving head wash that's brighter, and has a similar zoom range, and saves getting ladders out?

I think it is technically a fresnel lens - it's a holographic type thing like in a parnel. The "grooves" which you'd normally see in a glass lens are there but they're really really small. The (only) advantage of these type of fixtures over a MH wash is the barndoors which are useful for theatrical purposes. However when using barndoors with this type of lens you don't get a nice edge, it's all a bit messy.

Au contraire, Blackadder....I was pleasantly surprised at how good the barndoors were on this demo unit- aside from the OW intensity, you wouldn't have known the difference, little to no obvious colour fringing. MLs are not an option for this application, like-for-like replacement is what I need to do, whilst also bringing the equipment up to date. (IE, small form factor LED fresnel, or fresnel-like unit.) Thanks, Ian Edited to add, Paulears, not sure where you're getting £500 from- I was quoted around £300 form the rep.
alistermorton Posted May 25, 2017 Posted May 25, 2017 How do the colour tones compare with gelled tungsten, and are they quiet enough for a rig full in a quiet theatre performance?
Bryson Posted May 25, 2017 Posted May 25, 2017 Also, Americans haven't the slightest idea what a PC is. Seriously. I have three rogue Starlette PCs and I have to explain them to people with decades of experience. They're just not a thing over here.
p.k.roberts Posted May 25, 2017 Posted May 25, 2017 not sure where you're getting £500 from- I was quoted around £300 form the rep. Not even that - only £230 from CPC at the moment. I'd certainly be very keen to know what you make of them if you do go ahead and buy them ...
paulears Posted May 25, 2017 Posted May 25, 2017 Google search - first few results. £230 seems quite cheap doesn't it. I look forward to the reports - and of course going RGBW, tends to give you 3 more lights as with the conventional use of Fresnels, you have probably 2 or 3 colours per area in stage - so 6 Fresnels could be covered by just 2 RGBW ones - so as you tend to swap 1:1, you end up with more useful lights, better washes and better variety - if brightness wise they hold up. Still not convinced on lenses = but those ones on OHPs were always described as Fresnels, weren't they.
Guest Posted May 25, 2017 Posted May 25, 2017 For the price these sound like nice little units. As mentioned be very interested to hear thoughts on them if you purchase. but those ones on OHPs were always described as Fresnels, weren't they. Yes I'd never thought of that but the light plane where you place the acetate is a Fresnel lens.Edward
kgallen Posted May 25, 2017 Posted May 25, 2017 Edward - get off it will yer! You're not old enough to have ever seen an OHP let alone a working one! The last one went to the great acetate grave in the sky years before you arrived on Earth! http://www.blue-room.org.uk/public/style_emoticons/default/wink.gif

But not seen an epidiascope for a long time.
sleah Posted May 26, 2017 Posted May 26, 2017 One of our old OHPs is used at least once a year for set painting.Quick easy way to get a design on to a flat - anyone can follow the projected lines (usually parents in our case), you just need someone with a bit of artistic skill to produce the acetate.

That's exactly what 3 of my hires are for. :)
tomo2607 Posted July 6, 2017 Posted July 6, 2017 Sorry to bring up an old post, but Ian, did you end up buying these? We are looking to purchase 6 for our schools theatre. I’d welcome a brief review if so.
