Unlike flashguns that provide short bursts of light, LED panels are a camera accessory that deliver a constant source of illumination, often with various extra options.
You may be considering adding a panel to your setup but want to weigh them up before taking the plunge. With that in mind, we've had a look at six current models to see which offers the best value for money.
It may be the baby of Rotolight's range but with variable colour temperature range, high power and its extra features the NEO 2 is our winner.
Check out the competition below.
1. Rotolight NEO 2
Rotolight's second-generation NEO model is a genuine gamechanger
Colour temperature: 3150-6300K | Lux (at 1m): 1840 | Power source: 6x AA batteries, D-Tap port, AC adapter | Dimensions: 150x45mm | Weight: 1,293g (boxed)
The Rotolight NEO 2 is rated for a whopping 2,000 lux maximum brightness at three feet (91.5cm). We couldn’t quite match this, measuring a peak 1,840 lux at 4,000K, but that’s still noticeably brighter than most competitors. Brightness does drop to around 1,100 lumens at each end of the 3,150-6,300K temperature range, but this is the only issue we found. The dual control dials adjust a plethora of easy-to-set options. Six AA batteries sustain 90 minutes of full-power continuous illumination, or there’s a mains input. You can even use the NEO 2 as a flash, with up to 500% more brightness than in continuous mode.
2. NanGuang CNLUX1600C
At this price, is this panel too good to be true or an absolute bargain?
Colour temperature: 5600-3200K | Lux (at 1m): 1005 | Power source: 6x AA batteries, L-type li-ion, AC mains | Dimensions: 141x95x40mm | Weight: 175g
NanGuang’s offering is power rated at a potent maximum 1,600 lux, and it’s also colour adjustable, with a 3,200-5,400K range. Two dials set light power and colour temperature, with one dial controlling the power of the 3,200K LEDs and the other operating the 5,400K diodes. To get a colour temperature in between, you’ll need to balance both dials, which can be fiddly. Crank both to the max and the LEDs give a 4,100K combined output, which we measured at a blinding 1,720 lux, though this does drop to 950 lux with only the 5,400K LEDs active, and 826 lux at 3,200K. Light spread is average, matching the Metz’s 420 lux reading at 30 degrees, but falling off beyond that.
3. Metz Mecalight L1000 BC
Features include built-in Bluetooth
Colour temperature: 2800-5700K | Lux (at 1m): 1000 | Power source: 6x AA NiMh, L-Type Li-Ion, Micro-USB | Dimensions: 154x100x460mm | Weight: 245g
Metz engineers have tuned the Mecalight L1000 BC to output a consistently high 1,000 lux brightness at one metre from 2,800K through to 5,700K. And it works: we measured a constant 1,180 lux across the temperature range, and an impressive 420 lux at around 30 degrees off-centre. Given this attention to detail, and the presence of a small OLED display on the rear panel, it’s a pity the colour temperature readout is very basic and not quoted in Kelvins. Like the Croma2 (below), power can come from an L-type li-ion cell or 6 AA batteries, but the latter are inserted into a bulky – if waterproof – holder that sticks out from the back of the panel.
4. Manfrotto Croma2
Smartly designed unit with a decent light spread
Colour temperature: 3300-5600K | Lux (at 1m): 900 | Power source: 6x AA batteries, Li-ion L-Type | Dimensions: 440x108x170mm | Weight: 300g
The Manfrotto Croma2 offers adjustable colour temperature, which can fluidly transition from 3,300 to 5,600K. Both temperature and power are adjusted with simple dials with no scale markings, so repeating the same settings from shoot to shoot is difficult without a light meter. We recorded light power figures of 750 lux at 3,300k and 900 lux at 5,600K. With both sets of blue and yellow LEDs active at 4,550K, brightness peaks at 1060 lux. Despite a quoted 50º beam angle seeming slightly narrow, real-world use demonstrates a decent light spread. Power can come from the mains, or through two battery options.
5. Lume Cube
Shuns the traditional concept of an LED panel
Colour temperature: 6000K | Lux (at 1m): 580 | Power source: Lithium-ion battery | Dimensions: 102x102x165mm | Weight: 322g
It may be small, but the Lume Cube is tough. The mostly metal shell feels very solid and able to shrug off plenty of abuse, and it’s waterproof down to 30m. There isn’t much room for controls though, with only one button to turn the light on and cycle through 10 brightness settings. Fortunately, the Lume Cube can be wirelessly controlled by your smartphone via Bluetooth. Somehow a rechargeable (but inaccessible) battery has been crammed inside, giving two hours runtime at 50% brightness. Light output is quoted at only 150 lux, but that’s from three metres. We recorded a respectable 580 lux at the more typical one-metre measuring distance.
6. Kaiser SmartCluster Midi
Comfortably smaller and lighter than most competitors
Colour temperature: 5800K | Lux (at 1m): 190 | Power source: Lithium-ion battery | Dimensions: 115x71x21mm | Weight: 135g (with battery)
Rather than using bulky AA batteries, the Kaiser SmartCluster Midi is powered by a compact, non-proprietary 1,800mAh li-ion battery that’s good for 90 minutes of full-power illumination. The battery is included, as is a basic hotshoe swivel mount, along with warming and diffusion filters. With a lighting power of just 190 lux at 1 metre, illumination is noticeably dimmer than the opposition. Power may be lacking, but the light quality is attractive, with a measured 5,700K temperature being very close to spec and looking pleasingly neutral. If you only need to light close subjects, or are willing to shoot at higher sensitivities to compensate for its low power, the SmartCluster works well.
