up using the smaller 2.1 as a backlight on interviewees, and for that purpose I’d be happy to have the bicolour version for ease and speed. The 4.1 was just about strong enough to give an background accent on a cream wall behind one of the interviewees in a room illuminated by a window - the daylight version would probably have been more effective. In my experience, I rarely use my AC dedos at full power, and often end up having to compensate for the resulting colour shift with CTB gels, so in most tungsten situations I don’t see the lower flood output being a problem, but the figures would certainly steer me towards the daylight version and I’d use CTO to match colours shooting indoors.   The focus ring works both to control light angle (the 4-5 degree tight beam is virtually the same as the AC DLH4) and to increase output. In a two-camera, low-key indoor situation without the fight against daylight, but with a huge fight against light spill from soft lights as keys, I was able to solve the problem by substituting with the LED hard lights as side keys, using the focus to increase the output to acceptable levels.  I didn’t have a chance to see how long by 95Wh batteries would power the lights for, but certainly for a one hour interview the charge display had only dropped about 30%. In tests the UK distributor says the 4.1 ran at full output for three and a half hours on an 130Wh battery, so the 2.1 should be double this.  Beam spread was even and constant throughout the focus range, and the multi-leaved barn doors are really versatile, enabling enough control to create light slashes or squared- edged shapes. Like the AC lights there are projectors available for ultimate accuracy and inserting gobos, and soft boxes for both fixtures. I could see a softbox being useful for conventional one-camera interview setups, with the 4.1 as diffused key, and the 2.1 as backlight either soft or hard.  The comparison with the 150W DLH4 output levels is interesting - see the table below. The data shows the 4.1 Bicolour is less powerful than either the DLH4 or the 4.1 daylight version, although it’s more powerful at 5500K than 3200K. The DLH4 comes out as a winner at both spot and flood, but notice that the angle of the flood on the LED is 12 degrees narrower, and thus the light beam may be more concentrated. How much does this matter for most shoots? In conclusion I found the Dedo fixtures absolutely lived up to the quality the brand name implies. There are other lights on the market at a range of price points and quality, but none has the unique patented design that produces the unique beam qualities we all know from the AC range. I would be happy to use them on just about any shoot in place of my AC versions.   Measurements taken at 1M DLH4 - 150W Tungsten head (4.5 - 48° beam angle) Spot: 13000 Flood: 3000     DLED4.1-D - 40W daylight LED (4 -60° beam angle) Spot: 24000 Flood: 1300 DLED4.1-BI - 40W Bi-Colour LED (4 -60° beam angle) Spot 3200K: 5000 Flood 3200K: 740 Professional Prompting on an iPad Turn your iPad or Android tablet into a full prompting rig.
