I’ve been wondering what the difference in color temperature is between a good tungsten light head, a good LED head, and a cheap LED head. The video is below.
Judge for yourself, but from what I see the tungsten is spot-on for good vibrant color. I used my little Lowell Prolight/cost around $120 but the lamps are fairly short-lived. Second up is the Flolight with 128 LEDs at a cost of around $260/runs cool with extremely long life. The Neewer, which comes in last, has 160 LEDs and cost only $30.
In the first test the Neewer is obviously green. This test was shot with my Panasonic AG-HMC150 on auto white. The Flolight looks pretty good, but is cool in comparison with the Prolight. Take a look at the upper right color square, which is an intense pink to see the difference.
In test #2 the Flolight comes even closer to the Prolight. In this test I white balanced each light on a white card. You’ll have to excuse the exposure here on the Prolight…it’s a bit dark. But you can see the obvious difference in the pink again in the Neewer.
In test #3 I white balance the Prolight on the white card. Then balanced the two LEDs on a warm card, which is intended to shift the color balance away from blue and towards a warmer hue. In both LEDs the reds are off and you can see the warmth in the grey scale at the top, compared to the tungsten card.
In the fourth and final test I used the Prolight white balance on white card and then shot using each of the LEDs with that same set white balance. This is where you see blatant differences between the full spectrum tungsten light and the LEDs, which shift to blue and totally lack warmth. And if you look closely you can see the greenish tint is more apparent with the Neewer head.
What does this mean to you? Well, this test was shot in a dark room with no other light invading…so you need to keep in mind if you decide to shoot with your LEDs in the dark there will be issues with accurate color. However the good news is if you shoot and use the LEDs for fill only AND if you white balance, the full spectrum lights will overcome the deficiencies of the LEDs. And I will say that being able to operate off batteries for extended periods with LED lights has given me a freedom I never had with the hotter tungsten lights, which are battery vampires.
Update from b-roll buddy Bobby Alcaraz. If you’re gonna use LEDs, make sure they’re all by the same manufacturer so they match. If you start mixing different (especially bad and off color) lights you are asking for trouble. At least with them all being the same you stand a better chance of getting somewhat usable color.
