ProLights Lumipix Batten

Looking at lights like this makes me wonder if we will soon see the demise of the gel industry altogether. I must admit that I hope we don’t, having spent years learning about CTO, CTB and the ever-amusing oddball amber (162) and seedy pink (748) amongst the plethora of other coloured gels available. I guess we will all get used to dialing in a colour on the back of the lights rather than correcting them at the front with giant sweetie wrappers and no doubt it will be easier, cheaper, and more accurate this way. I can’t help feeling we are likely to lose something of the craft of lighting along the way.

 

Still, far be it for us to stand in the way of progress, so we are fully embracing the new LED technology and it’s minimal need for gel. A good example of this is the new Lumipix batten from ProLights. This is a 12 bank LED light batten with the ability to produce more than 16 million colours without having to use a single sheet of gel. And I thought there were only 7 colours, well that’s how the rainbow works isn’t it?

Not only will the Lumipix display lots of pretty colours but it will allow you to do all sorts of combinations and effects with them. I feel that this has been designed with the stage in mind rather than the big (or small) screen. They would be perfect for concerts and that type of show with in-built microphones and adjustable sensitivity to allow for music mode where the lights will respond to music themselves. Also full Dmx control is available right down to the individual LED’s so you can change colours and make pretty patterns to your hearts content.

But before you tune out its not only rock bands that can use this, you image-makers may find them useful too. In our world we would think of them less as a disco light and more of an all-purpose flood or fill light.

Rather nicely they have a flicker-free operating frequency of 400HZ to allow for relatively high speed filming, and a LCD display user interface so you can play with the settings without having to put it through a complicated control desk.

IP33 protection and a maximum power consumption of 40W will keep the gaffers happy. You folks will also appreciate the minimal 3.2 kg weight and the robust aluminum body designed to disperse heat and also protect the lights.

Interestingly these battens are also capable of being “pixel mapped” This term describes how a bitmap or image can be displayed pixel by pixel on a series of lights thus creating a video screen of sorts. I presume this would be used for displaying simple moving patterns or images.

However, I can’t help thinking that this feature could be employed to make the ultimate big HD screen experience. As each unit has 12 x LED lights, I calculate that 158 ½ units side by side would do one line of a HD display and about 170 thousand units stacked up would complete it. What an impressive screen that would make, being 150metres wide, however, you may have to watch it from outer space. Anyway we don’t quite have enough of them for that and even with the minimal 40 w max power draw per unit it would still draw 6912000.00 watts in total that’s over 30 thousand amps.

As far as specifications go each unit has 12 tri colour High-efficiency CREE LEDs giving a LUX of 1360 @ 1m, the optics give a beam spread of 19 degrees. Several DMX selectable configurations are available (2,4,6,7,9,18 or36) for advanced or basic controlling. A tough aluminum body to aid with heat dispersal and a controllable fan for forced ventilation will prevent over-heating.

Each unit has twin brackets for hanging that can also be used for floor positioning.

A power output has also been built in to allow for up to 10 units to be joined together using the one 230-v supply (less distro required)

So all in all this is a very nicely thought through product with some great features and I will give it a 7 / 10 for my Brucie Coolness Rating, only slipping slightly because its too difficult to ride home with on my bike for parties.

 

Cheers all BB

Litegear LiteTile 8×8 LED

Welcome to the new year everyone, we hope you had a great Christmas and a relaxing break and are now ready and waiting for the next twelve months of fun and games.

Now the new year seems to have brought with it a bit of a cold snap so with your best interests in mind as always we would like tell you about one of our Christmas presents to ourselves, a rather fetching blanket.

Yes we know that blankets tend to encourage you to stay in bed normally but not this one, in fact this one is definitely worth getting up for.

The brand new Litegear LiteTile is something rather special and we had our first play with it yesterday and we’re very impressed. We already have a good range of LED lights from Litegear and they are proving to be popular with you folks but this one is bigger and better than anything we’ve seen so far.

Imagine a flexible blanket of Bi colour LED’s that’s 8 foot square and what that would allow you to do. Now stop daydreaming because it’s here now waiting for you to enjoy.

I have to admit that personally I’d like to take it home and use it as a blanket on my 12 year olds bed, I cant help thinking that waking her up in the morning would be easier if I could make her whole bed light up at the flick of a switch!

To get a bit technical for a moment the LiteTile 8×8 actually consists of four 2×8 foot panels that can be configured to form a number of shapes, Velcro covered edges allow for each panel to attach to its neighbor or for that matter anything else that has a Velcro fastener on it. Also equipped with eyelets to allow for attachment to grip or butterfly frames as required.

Being made of hi-grade engineered textile the LiteTile is flexible enough to be configured round curves, folded, scrunched up and so on making them a truly versatile product.

As far as light is concerned the LiteTile is equipped with new CineMitter LED’s which boast a CRI and TLCI* rating of 95+ along and a extended colour temperature range of 2600K – 6000K. All new DMX enabled dimmers are supplied giving full local control of dimming and colour temperature or allowing for connection to a control desk.

Everyone will want to know what the maximum output is so for the record the LiteTile gives out a very useable and impressive 20384 lumens (that’s bright to you and me)

When it comes to powering, it’s not much more difficult than plugging in your electric blanket, granted it uses 16 amp leads but we have plenty of jumpers if you need to use a 13amp domestic outlet. Each of the 4 2ft by 8 ft panels has its own power supply so they can be used independently and we will shortly take delivery of a single power supply to run all four units together. A V-lock battery option is muted in the future and no doubt we will get one as soon as it’s available but this may be a while before it hits the market. The individual panels each have a header lead of 7ft or 2.1m in length, giving you plenty of scope to position the supply out of sight.

So if you’re in the market for a large flexible soft light then this could be what you are looking for and now you know who has it you’re really running out of excuses.

Litegear also make a 4 foot version but as you can fold the 8 foot in half and keep using it I don’t think we will rush to get the smaller one, bigger is better anyway.

The all important BCR (Brucie coolness rating) for this has got to be at least an 11 out of 10, its portable, powerful and versatile all of which are great attributes, but its also very cool and I rather like it. I can’t help but wonder what LED’s will turn up next, anyone got any suggestions?

You could take it to Glastonbury this year just to make finding your tent easier.

Thanks for reading.

 

 

TLCI means “Television Lighting Consistency Index” it’s calculated using a spectroradiometer and is a measurement of a luminaires spectral power distribution in the context of television. The results can be checked against the table below. Hopefully you all feel as enlightened and excited by this as we do.

 

 

85 – 100 errors are so small that a colourist would not consider correcting them
75 – 85 a colourist would probably want to correct the colour performance, but could  easily get an acceptable result
50 – 75 a colourist would certainly want to correct the errors, and could probably  achieve an acceptable result, but it would take significant time to get there
25 – 50 the colour rendering is poor, and a good colourist would be needed to improve  it, but the results would not be to broadcast standard
0 – 25 the colour rendering is bad, and a colourist would struggle for a long time to  improve it, and even then the results may not be acceptable for broadcast

Chroma Q Space Force

Let’s start this blog with a little question,

What has Britain’s Got Talent, The Royal Shakespeare Company, The Welsh National Opera, Kaiser Chiefs, The Killers, Stereophonics, Michael Buble and The Eurovision Song Contest all got in common?

Some of you folks may have guessed it’s something to do with lighting and you would be correct, no prize however as with this being a blog about lighting it wasn’t really hard to work out, was it?

So yes all the above artists have recently used lights by Chroma Q to add some light to their performances

Chroma Q have been producing high quality lights since the mid 1990’s and launched into the LED market in 2004.  They have a good reputation for producing award winning premium LED lights for concerts and theatre productions, retail and leisure, museum installations, exhibitions and so on.

Today I want to draw your attention to the nicely named “Space Force” soft light.

This latest offering from Chroma Q is a rather nice take on the good old space lights but now in LED form.

It only seems like yesterday when the LED lights made their debut on to our photographic world but we are already getting so used to them and the many advantages they offer us in the production side of things. It’s hardly necessary to explain the cool running reliability of LED’s or the 100% dim-ability and full colour temperature adjustability from 2800 – 6500k, so I won’t, but suffice to say the all new Space Force from Chroma Q has all of this.

Space lights are designed to flood large areas with lots of lovely uniform soft light and to do this they often have to be quite powerful and hence tend to run rather hot.  Historically they also require diffusion, usually in the form of a softbox or lantern.  Also as they tend to be pointed straight down heat can be an issue, only some lights are able to do this without “cooking” themselves. Rather nicely the Space Force produces an output of up to 26,700 lumens roughly comparable to a standard 6k fixture and without any form of extra cooling required they won’t cook themselves even if pointed down and with no fan required they run (almost) silently.

Diffusion is built in as with most LED fixtures so you don’t need to add anything else (we do have an egg crate and a lantern available to fit if you need). In normal operation (without the egg crate) it will give you a 60-degree beam angle.

Best of all (well as far as our drivers are concerned) its only 8kg in weight, so it’s easy to handle for its size, our unit comes with a yoke for mounting but also has options available to hang or stack numerous lights together.

Full onboard controls are on the rear of the unit allowing for complete stand-alone operation and just in case you need it full DMX control is also catered for.

Other nice functions include a “focus” button that causes the unit to revert to a pre-set intensity for when you need to check your focus (ok I had to look this up as focusing a space light seemed a bit of an oxymoron), 2 useful memory functions are available allowing you to “store” the settings on the light for recalling later.

Don’t be fooled by the name Space force or the term Space light, yes this is a space light but its far more use than that and can be put on a stand and used horizontally as a lovely simple soft light. All of our units are fitted with a yoke to allow for this sort of operation.

So in summary this is a lightweight, cool running, quiet and yet very powerful space light all of which make it an attractive alternative to the regular units. With impressively high CRI figures (up to 97) and a fraction of the energy consumption of the non-LED equivalent light (331w at 230V) it’s sure to be a winner.

The Space Force has already won an award at the Cine Gear Expo Technical Awards coming in first place however, I bet they are hanging on my BCR score, so here it is, 8 out of 10, that’s one point for each side as it’s an octagon, it’s a polygon too but that’s something to do with a missing parrot so I won’t go there.

Oh and we have forty of them ready and waiting for you so don’t look any further than Pixipixel, no matter how big your lighting needs are.
