Aputure has some of the most popular LED Panels available for the budget shooter, and now they've added a nice high power single point source LED Light called the LightStorm COB120. If you've worked with Fresnels, the new COB120 can be used in similar ways. Still photographers who are now working with continuous lighting will also be familiar with it's MonoLight type form factor. With a Bowens Mount adapter, you'll also be able to use many available Light Modifiers such as a Beauty Dish, Softboxes, Snoots, etc.
NAB 2014 Drew with Alzo Video talks about the upcoming additions to their popular High Intensity LED Video Lights. These lights are not using multiple standard plastic lensed diodes common with most flat panels adding additional benefits with this design.
The High Intensity LED can provide a true spot or flood with the optional fresnel lens and can be flagged using barn doors without multi-shadow issues. If you're a photographer who has worked with strobes, you'll notice the strobe-like design make this compatible with hundreds of light modifiers already available from softboxes, grids, snoots, strip boxes, dishes, and more.
Mike Peterson writes in and shares his opinion on those new LED video lights that are being sold online as 1000w LED Fresnels. So far there really hasn't been much complaint over the actual build quality, as they are using the same aluminum housings as the 'As Arri' light kits (seen here) with a high power LED inside. Others have already confirmed these are not equivalent to 1000w, nor is it an actual Fresnel light (no proper glass element), but Mike thinks it's still a great solution for a bright low power / low temp light source. [Thanks Mike]
With most artificial light sources there will often be a green color cast, but can be corrected with a minus green (magenta) filter. The benefit to LED lighting is the ability to plug several at any location without blowing out circuit breakers and generating too much heat in the environment. You can also use low temp colored Gels (cheaper stuff) over the LED lights without the worry of it melting. Something you really need to think about if you're trying to use a few hot Tungsten or Halogen type lights. You can find this exact lighting kit, and other LED Fresnels via eBay (click here).
Jesse writes in and shares some new LED Video lights in the form of Fresnels [Thanks Jesse]. One unit looks to be using the 'As Arri' style housing. To be more accurate, one of these units do not provide an actual fresnel lens, so it would be considered more of an LED spotlight. Both units stuff a 100w High Power LED inside that should offer an equivalent power output of a 300w tungsten bulb.
The other more expensive unit appears to offer the fresnel style cut glass to focus the beam. I think it's still too early to invest in such lighting, but hopefully in the coming year we'll see more of these lights being offered bringing prices down and quality up. You can already find some of these LED Fresnels available via eBay (Click Here).
