I made this one for filming for many projects in University. 

 

Before I used some typical Flo-tube which give green spike on Daylight WB (5200K on Canon DSLR).

 

Later on I used Osram StudioLine 55/5600. Pretty great light but some how skin tone looks a bit off and cast Magenta (actually they maybe intended to used in studio just like there name for Chroma key lighting)

The most fascinated tube for me is TL-D Graphica 950 from Philips which rated at CRI 97 with CCT 5300K.

Matched perfectly with Daylight and give really good skin tone. I loved this more than real Kino bulb which sometime cast Magenta as they designed for higher power rated.

 

Thank you.

What do they cost? Do they make the same thing in 4' 36W?

I flee in terror from $20 a tube when they're so alarmingly easy to break!

 

And I'd need 16 tubes to relamp all my stuff. Ouch.

 

I use protective sleeves on mine - not so much to protect them from being broken, which is difficult, but to contain the mess if they are damaged.

Yes, It's really fragile especially with 4ft or more. I almost be a gaffer in the team, Look after this fragile stuff. 

 

If you buy bulk of it. the price will go down as in Thailand here go as low as $120 per 10 tubes.

 

I've also look at some LED tubes but none of them offer quality light as I expected, Useless green cast and poor skin tone.

The TLD-950 and TLD-930s are great tubes when filming in offices or anywhere you want to keep practical fluros on, but want don't want green/magenta casts. Have spend many hours swapping out domestic tubes for TLD950/930 tubes. They're a pretty nice match to kinos.

I wouldn't uses these day in-day out in kino fixtures, with kino balasts, as kino ballasts over drive the tubes(the kino tubes themselves are designed to be overdriven as opposed to a standard tube) and the rendering gets a little inconsistent once the tube gets hot. Also the fragility of the tube doesn't really lend itself to the wear and tear being used arround set.

I use these.

I get the impression they're really intended to allow people to maintain standards required for food preparation areas - hence the blue - but they serve to avoid throwing glass and toxic chemicals everywhere if you break a tube.

 

They look tougher than they are - the plastic is very thin and you can compress the tube between a thumb and forefinger, so it's more about mess prevention than actually making the tubes tougher.

 

Yes, kino ballasts will make standard tubes emit more yellow.

Wow! That's what I looking for. Thanks!

 

Also, Graphica is much greater continuous spectrum than normal TL-D 9XX. but as many used it's likely to be same.
