yes.. it really does what a baby kino with a daylight bulb does.. it wont light a room but it will definatly add a few stops where needed.

Re: Home made DIY LED baby light
Hey Zoom, can you do a color balance test, so we can see how it matches to daylight?
Just go in a dark room, use only your light, and shoot a piece of paper twice: once on 5600k preset, and once on manual white balance, so we can see how close the color temperature matches... thanks!

Re: Home made DIY LED baby light
hey Barry here you go.. the preset is a little dark as it was a seriously low light sample.
Light off.. Manual WB
Light on.. 5600 preset
I also backed up a bit, to try and get the ring of the light.. you can see it does a little drop then raise in temperature on the outside edges

Is this what I think? The second is with the LED's on? A WB on a white board in a dark room? WOW! Zoom needs to change his name to: ZEUS (Is that how you spell the Greek God name?)
So, this would mount on DVX, and one can use it add stops to your talent or while shooting a close up?

I am so the last person on the planet that needs to try and make anything with electrical components. I can juggle though.

Re: Home made DIY LED baby light
yes the second one is about as white as it gets.. in fact its a pretty nice curve on the scopes.
The room is pitch black... I had to open the door for the first one to allow enough natural light in for it to read.
And I am pretty impressed. Im actually gonna make a smaller one with the LED's more close (the array right now is pretty random) I absolutely dig how I can just snap on one of the standard DVX batteries to power it too.. nice not to have to carry around a different cell.
An important note is that you need to get the Right LED's... some ultra brights are over pumped and produce a lower color temp.. almost yellow.

Re: Home made DIY LED baby light
I know we are always asking you to "post" examples. But I would love to see a grab of an object (preferably a person but I understand) shot in natural available light with and without this little bad boy on.
In fact, an EXT and INT examples would be great.
It's requests like these that make Zoom activate the CREDIT CARD payment option.

Re: Home made DIY LED baby light
Hmmm. According to PhotoShop, that white is ultra-mega-pure white. If those LED's are putting out a proper 5600k-balanced white light, I'm gonna have to get me some of them...

Re: Home made DIY LED baby light
here is a little sample...
Barry, I think that it is not dead on 5600k.. I think it is a little cooler above, probally in the 5800-6000k range. an 1/8 CTO may bring it dead on though...

sounds right... I chucked the little baggies though. they are the 8000mcd ones.

Re: Home made DIY LED baby light
What kind of range do those LED's have? Do you have any fluo's you could test against?
I thought the LED's might have a very short range. Do you have a lightmeter where you could measure FC at various distances?
Wonder how long they'd last on a 9v battery... I lit a Halloween scene using taplights in various places, made for a nice weak soft source. Your LED kit looks a lot punchier, and a lot smaller. We used a track lighting kit for our "matrix" set, but those LED's might make for a lot more convenient placing. I gotta order one of those kits and fool around with it.

Re: Home made DIY LED baby light
Hey Barry.. I can bring out the lightmeter and test.. but the throw isn't bad for 24Led's... On the same PC board I could put about 50 and it would get pretty bright... it is a little blinding already.
As for fluo's I dont own a kino kit but I do have a 2 foot single I can test it against.
As for battery test.. I am testing that right now, It been on for about 4 hours already on that DVX battery.. I have no idea how long it will last. These LED's though are not the normal LED's.. I originally bought a strand of those LED christmas lights and once of these LED's has the brightness of almost the entire strand.

Re: Home made DIY LED baby light
I just took a quick reading against a 60w incadesent household.. they both have exactly the same readings at 6'... remember though that LED's are very directional.. untill I figure out what sort of reflect / diffuse to put in front of it it will be a little hard to test.

Don't KINOS usually have a reflecter type back base?
