Utilizing efficient but 60% brighter 580W LEDs and a 14" diameter Fresnel lens, the DeSisti Super LED F14HP Tungsten Fresnel Manualfrom DeSisti Super LED F14HP Tungsten Fresnel Manualcan replace a 5000W tungsten Fresnel fixture and provide a versatile spot-to-flood beam angle of 12 to 51°. The specialized chip-on-board LED array offers a high CRI/TLCI of 97/96 - an indicator of superior accuracy in color rendering. The unit is also DMX controllable with smooth dimming from 0-100%. It has a high-efficiency Self-Stabilizing Active Cooling system for thermal regulation and a durable, lightweight carbon steel housing to protect the electronics. In addition, it has a built-in universal 90-240 VAC power supply for worldwide use and comes with a 4-way barndoor set and a color frame.

14" (350mm) diameter high quality, shock resistant Borosilicate glass Fresnel lens on spring supports.

Rugged and lightweight carbon steel housing with low glare black epoxy powder coating, with internal double walls and reinforcement.

High-efficiency, self-stabilizing, active cooling. Automatic, thermal stabilization of the LED operating temperature is managed by an internal thermal sensor and CPU, variable speed fan, and heat sink to maintain the LED array's constant temperature at a maximum of 149°F (65°C). The hydrodynamic bearing fan operates silently with a very low RPM.

Special patented optics for LED technology.

Helix screw driven focus mechanism which guides Teflon bushings supports the LED engine along 2 rods. This ensures smooth operation during focusing, in any tilted position of the fixture. The Teflon bushings also provide a wiping action, which cleans the steel guide rails during focus. The focusing mechanism can be activated from both front and rear of the fixture and the entire spot-to-flood action is accomplished with 1.5 turn of the focusing knob.

The unit is equipped with a hinged lens door with a wire-guard and includes accessory holding brackets. One of the 4 brackets has a locking knob and is spring loaded; it can be locked to safely hold the barndoors, color frame and scrims.

Q: 3. how many lumens?

A: Apparently it's a closely guarded secret. Arri does NOT publish any information regarding comparisons of their Full Color L7-C -vs- their L7 (Daylight or Tungston versions) Not sure why we are not getting exact lumens figures for many of these new Led luminaires. It is one of MOST annoying aspects of this move to teh new technologies that the manufacturers are simply refusing to give out any information other that (oh it's roughly like4 a 1K or a 650 Fresnel) Not very scientific ARRI. Please get on the ball Arri and publish precise metrics on these lights. If they are going to ask $3000 for an Led fixture, they at least can produce some detailed information about these lights. It's been a frustrating process getting a straight answer from anyone regarding these lights.

Q: 4. What's the tungsten wattage equivalent?

A: According to the manufacturer, this light is a 700 watt equivalent.

Q: 5. Does this work with ARRI 650W?

A: This one will not. These two will, one is 5000k the other 3200k https://bhpho.to/2T1tkak.

Q: 6. What is equivalent of brightness of this Lighting of daylight HMI and tungsten lighting?

A: They say it's equivalent as a 1.5k. I would say that in my experience it seems similar to a 1k tugnten fresnel and falls somewhere btw a 575 and 1200w hmi daylight (par lenses). It's pretty tough - the weak point is that the focusing barrel is made of plastic and can break if dropped or not protected. The best part about this light is that it can do any color. I'd purchase again.

Q: 7. Can I fit 3 of these into a ARRI 571197 Heavy-duty Location Case?

A: NO, this is made for smaller lights

Q: 8. Can I plug this light directly to wall outlet?

A: Yes

Q: 9. What is the smallest Pelican Case that can fit the Arri L7 with its included accessories?

A: The smallest Pelican case I can recommend to hold an Arri L7 with accessories is the Pelican 0500 Transport Case (Black) B&H # PE0500B.

Q: 10. where are the barn doors for the Fresnel 150?

A: Barn doors are an accessory, and need to be purchased separately. You may also want to purchase some scrims and a spare bulb.
