Specially manufactured for LEDs, this 24 x 24" Rosco OPTI-FLECS 0.6ND Filter 24x24"has a neutral gray hue and is mounted on light fixtures to reduce their output by 2.1 stops of light.

2.1 Stop Light Loss

The low-heat feature of LED lights means that gel is not an expendable any more - it's an accessory, just like a scrim or a barn-door. OPTI-FLECS is a semi-rigid filter that offers cinematographers, gaffers and lighting directors a durable, reusable solution for correcting the problematic color-rendering aspects of LED lighting.

Related Questions and Answers

Q: 1. How well do these stand up to heat?

A: Ive used clothes pins to attach these to Arri 1ks that get WAY too hot to touch and they dont even show the slightest signs of melting. They stand up to high heat cinema lights.

Q: 2. Can I configure the EVO 16 outputs for 5.1.2 Atmos mixing?

A: While the Audient EVO 16 24x24 USB Audio Interface offers the correct number of outputs for surround mixing, it does not offer any surround monitor control or room correction capabilities and would need to be used with a separate surround controller in this scenario. Similar interfaces with this functionality built in are the Antelope Galaxy 32 Synergy Core Interface (BH #ANG32CD), the Avid Pro Tools | MTRX Studio Interface for HD and HDX Systems (BH #AVMTRXSTU), and the Focusrite Red 16Line (BH #FORED16LINE).

Q: 3. Can you clip these to the barn doors of an Arri 650 + without it melting like the other cheap gels?

A: You can use these on a Arri 650w. They are high quality and will last longer than budget gels however they are consumables, they will deteriorate over time.

Q: 4. I see they handle the heat if clipped to barn doors. I have several 1k PAR-60 fixtures that have the typical theater gel frames on them. The gell frames are about 10" in front of the bulb but they get very hot very fast. Will these Rosco gells hold up to an old school 1K PAR-60 tungsten light when used in the gell frame?

A: It is best to put as much space between a gel and a light as possible. These are heat resistant but they can still deteriorate https://bhpho.to/3a3LAHT. Gels are consumables and will often need replacing when used with hotlights.

Q: 5. Are these soft gels (like off a Rosco roll) or are they rigid hard gels that are plastic?

A: Thank you for your reply.

Q: 6. Are these filters totally transparent or are they just translucent for lights only? In other words, can a picture be taken with them? Thanks.

A: It sounds like you want to put it in front of your lens instead of putting them on a flash or strobe. If that is the case, I would say yes, it will work from an exposure perspective and will reduce your exposure by a 1/4 to 1/3 of a stop. BUT... these are not optically perfect like a screw on yellow filter for black and white might be. The wavelength of light you would filter with these filters would not be uniform or constant and would introduce distortion across the light spectrum. These will never be a substitute for optical filters but they would produce an interesting effect.

Q: 7. Does this kit have CTB, CTO, Green and Minus Green filters? I need them more for color temperature correction than for effects. Thanks in advance!

A: No, the kit consists of; Lux 02 Amber Filter Lux 12 Straw Filter Lux 16 Light Amber Filter Lux 17 Light Flame Filter Lux 21 Golden Amber Filter Lux 26 Light Red Filter Lux 33 No Color Pink Flter Lux 44 Middle Rose Filter Lux 47 Light Rose Purple Filter Lux 51 Surprise Pink Filter Lux 60 No Color Blue Filter Lux 65 Daylight Blue Filter Lux 80 Primary Blue Filter Lux 89 Moss Green Filter Lux 93 Blue Green Filter

Q: 8. Is USB-C cable included?

A: The Audient EVO 16 24x24 USB Audio Interface includes a USB Type-C to USB Type-A Cable with purchase.

Q: 9. are there attachments to put into a godox ad600 pro?

A: To use these gels on the AD600 Pro, you can use the Aputure Barndoors, Grid, and Gel Holder for LS 120d/II and LS 300d/II LED Lights, which has a built in holder. On the other hand, there is also a specific gel kit such as the Flashgels Creative Color Gel Kit for Godox AD600Pro and Flashpoint Xplor 600Pro Strobes, BH # FL600PCREATV which fits to the glass dome. That being said, no holders are required. https://bhpho.to/2KeijTg https://bhpho.to/2SpbBh8

Q: 10. Can the 2 AES50 connections be on different sample rates? I.E. can it be used with a PRO-X console for FOH and an M32 console for monitor?

A: To use this device with both consoles, you would need to use this network bridge to make the sample rate changes, BH #KLDN9650.
