Z1 with Lite Panels
 

Anybody can please tell me if I can use these lite panels (http://www.litepanels.com/main.html) as an on-camera lighting for my future Z1?
Can they be fitted ? Arr they any good ???
Thanks for any help.

I liked em'.

Douglas,
thank you so much...great review...Looked like a great buy but now I will for sure buy it !

That price is insane. I would go for a Kino ring light instead. ( also high but better value)

I guess the single light for $700 is not that bad...the package for over $2K is a little deep...

I have to agree the pricing is insane. But LED lights should be coming out of the woodwork like mice at NAB

I hope so David, I've been wanting litepanels since we met a crew using them in St. Louis last Summer.

I disagree, the Litepanels are much more flexible and handy in the field than a Kino ring. See my DV Mag review at

John, do you know how much light you loose if I add a 3200K filter to it?

A typical 3/4 CTO (convert 5500°K daylight to 3200°K) has a transmission of 58%.

Going the other way, a full CTB (3200°K to nominal 5500°K) has a transmission of 36%.

Thanks for the info.

Though it lacks barndoors till NAB, here's a solution from IDX. It throws a lot of light from what appear to be 3 LEDs. They must be a newer generation form the dozens used in the litepanel.

Lot cheaper too.

The IDX web site has no photometry information other than the claim that the unit is as bright at as 35 watt halogen. I wouldn't hasten to compare it to the Litepanels without a hands-on test and more photometric info. The build also looks like cheap plastic as opposed to heavy cast aluminum.

Part of the reason that Litepanel uses an array of LEDs is to slightly soften the light -- the IDX will be hard light, and if you put a diffuser over it the diffuser will eat up a lot of the light.

I checked it out over the weekend. It throws plenty of light. Plastic housing yes, but not at all flimsy. I felt it could be a lot smaller. But its 3 led's throw much more light than the led's on the litepanel. It needs barndoors, with a swing on diffuser and W85 filter.

I'm just suggesting that while the litepanel is a heck of a good idea, it IS expensive and it does have it's weight issues when used with an NP1 on a small camcorder.

What we NEED is a Frezzi micro pro form factor with leds running on 7 volts and powered by a tap on a 7 volt camcorder battery. Who gives us that will rule.

If those who are going to NAB see it there, please post immediately. (I leave for a shoot in India on the 28th.) If you don't see it, work on the lighting manufacturers by appealling to their profit motive.

Build them
 

I am trying to source a handful of white LEDs to build a litpanel... there is no reason that they need to cost $2K.

I am guessing that the dimmer is wired up to an adjustable 3 pin voltage regulator. I will post results when I get the first one built. I think a wide array with a pice of Opal diffusion would beat the heck out of a Anton with less power consumption to boot.

We had this discussion over a month ago and I wonder if anybody has a better solution than Lite Panels....They should be great but the on camera kit with bettery is already $1000....I am rethinking my original idea because may be it is a bit too pricey...ANy other GOOD solution ???
Thanks

KinoFlo seems to have a beauty light that is around-the-lens ring.

They have it in both indoor and outdoor light settings by changing the fluorescent bulbs. I remember they advertised the unit to be powered by the camera's battery.

Is that what you're after?

Thanks Alex for your quick answer....I usually will use the matte box on the camera so the ring will not be a good idea....
Any good on camera light recommedations by anyone ??? I got my Z1 yesterday and I am pretty excited...I just need a good light.. for example in a museum where I need to light the person I am intervieing that sort of use I need it for...

I have been using a Lite Panel and find it puts out a very soft light with enough punch to work as a fill light in overcast outdoor light or as a camera/eye light mounted on a Noga arm. The thing I particularly like is that I can power it from my Z-1 batteries through a power transformer available from Lorne Lapham Sales and Rental (www.llsr.com). I have found that the NP-F570 which came with the Z-1 will run my Lite Panel for about 1 hour 50 minutes before the Lithium Ion battery shuts down. Li-ion batteries have a factory shut-down circuit when they get warm. The battery and transformer setup is small enough to fit in a shirt pocket and weight only 220 grams or almost 8 ounces. When shooting on the Z-1 I only need one type of battery and charger, which is a great advantage when you are travelling light.

By the way, I believe that LEDs are often dimmed by limiting current and not voltage. I am not certain if this is the case with Lite Panels, which will run on voltage from 5 - 24 volt. Dimming is achieved in many LED devices by chopping the current, essentially turning the LEDs on and off at very high frequency. This is possible because they come to peak output almost instantaneously. You can't see the very high frequency strobing but the perceived light level is reduced.

Size of the whole rig is a great advantage. The Lite Panel, LLSR power adapter and 4 feet of curly cable all fit into a Pelican 1060 Micro Case weighing 2 lb 8 oz including case.

Comparison to Kino-Flo 12 inch Mini Flos: I have used the Mini Flos for several years, both mounted on a stand and velcroed to a matte-box. Until the Lite Panel came out they were my favourite on camera lights. Mini-Flos are great, a single unit can be run from the NP-F570/LLSR power adapter described above. Mini-Flo draws about 0.8 amps in comparison to the Lite Panel 0.6 amp. A Lite Panel without any diffusion puts out about 50% more light than a 12 inch Mini Flo. Soft frost on Lite Panel is pleasing. The real drawback for travelling doc shooters, in my experience, is that the Mini-Flo tube is fragile (so you will want to pack and cary spares, and the unit, while light, is relatively large compared to L-Panel.

Lite Panel seems very robustly constructed other than the dimmer switch, which is flimsy and the tiny 1.3mm power plug which also seems fragile. Make up spare cables in different lengths and also one with a male cig lighter plug that can be plugged into a 110V AC to 12 volt 1000mA Class 2 transformer available from Radio Shack in Canada as Model SCP48-121000. This gives a light kit you can run off the wall or from your Z-1 batteries.

I am enjoying the DVINFO.net conversation.

Thanks Len...can you please give me a direct link to this power adapter???
I was told that the Z1 battery cannot power the Lite panel so I need to buy the battery,charger and the all one lite kit instead of the camera kit...I would pay $795 for the camera kit but has no intention to pay $1300 for the battery and charger etc....
Thanks

So does anyone know if LED panels were shown around at NAB? These Lite Panels are too expensive for me at the moment however I am receptive to alternatives...

Gabor,
Adapters for Sony InfoLithium batteries (one for style L for PDX170/170 and Z1, and another for the smaller style M used in PDX-10, etc) are made for Lorner Lapham Sales and Rental and info can be had from Brian Broz at brian@llsr.com I seem to remember paying a couple of hundred Canadian $ for the item. It is well built and the battery just snaps into it. With a 570 battery attached the whole unit can slip in a shirt pocket. Max output the batteries seem capable of seems around 1.5 amp. They have no problem handling the 0.6 amp draw of a light panel but are not reliable with a Marshall monitor.

$350
 

This one seems like a low cost alternative - does anyone have experience with it?

http://www.idxtek.com/x3.htm

$350 buys it here: http://www.bhphotovideo.com/bnh/cont...=365696&is=REG)

Also check this one - KinoFlo Kamio, which is a ring light, at $780:

How about this Frezzi ?? Is this a good choice?

Lite Panel Kit - For a Beginner?
 

John,

I'm relatively new to DV. I just picked up an XL2 and plan to shoot mostly interview / testimonial style video. I'm currently on page 75 of your book (found out about it in this forum), and wanted to know if you thought a nice lite panel kit would cover the majority of needs for indoor interview / testimonial style videos?

In your book, you seemed to look forward to advancements in LED technology - so is it advanced enough yet?

I like the thought of lite panels for their coolness, size and ease of using with electricity. Especially the later, as I have to admit that I probably would have blown the power out in my house if I had not read your Chapter 3 (Volts, Amps and Watts). Power requirements are important to me, as it seems the less power requirements you have, the less you have to carry around and have more options on locations to shoot (with ease).

I'd really like to hear what you think. I will probably be purchasing a nice lighting kit within a week or two. Thanks again for writing such a great book.

Not sure if it was just my camera, but the LitePanels light when mounted directly on the hot shoe plate made a buzzing sound when using the on-camera mic. LitePanels was baffled by this and sent me another one and it still did it. So, for on-camera use, I had to buy an Israeli arm which is a great addition anyways.

I posted this in another thread, but know that it doesn't put out a ton of light. I find that in certain situations (some daylight already in the room), that it does almost nothing unless you are very close to the subject. That said, LitePanels has announced a new light that is more of a spot light. Go with that one and use the diffusion if you need to soften.

I love the light, though, don't get me wrong. Great setup...

Kevin
