Do you need the intensity of flash, or the lasting attraction of a constant light? Would you rather have the stamina of a mains-powered kit, or the go-anywhere portability of a battery-powered lamp?
The Rotolight AEOS aims to keep everyone happy. It’s an LED-based circular constant lamp with a wide colour temperature range of 3,150 to 6,300K, but its killer feature is that it's capable of high-speed-sync flash.
- Easy-to-use control panel
- Rear-mounted digital display
- Ultra-high-efficiency LEDs
- Aluminium handles
- Tripod-mounting ball head
- Filter pack
- Power pack
The basic kit comes complete with an AC mains power pack, a sturdy tripod-mounting ball head with a 5kg load rating, together with a filter pack that includes neutral, cosmetic peach and magenta diffusers.
For getting out and about, you can add a clip-on 95Wh V-mount lithium-ion battery pack for £275/$300. It adds 720g to the weight but has enough juice to run the lamp at maximum power for three hours. The battery charger costs an extra £50/$55. Other accessories include an AEOS Yoke (£75/$85) for use with a lighting stand, and barn doors (£180/$195).
Switching to HSS flash mode, the AEOS can deliver double the maximum constant power output, along with instantaneous recycling. This means that you can fire a rapid burst of shots with flash, up to and including your camera’s maximum shutter speed and drive rate.
A major disappointment of many LED lamps is that they simply lack output power, but the AEOS is more impressive than most.
In our tests, even sticking to a base camera sensitivity of ISO 100, we could place the lamp one metre from the subject and shoot at 1/60 sec at f/4.5.
In HSS flash mode, the AEOS lived up to its ‘200 per-cent power’ claim, enabling an aperture of f/9 (one metre, ISO 100). Maximum light intensity is consistent throughout most of the colour temperature range.
It’s a powerful and versatile constant LED lamp with the bonus of HSS flash, but it soon gets pricey when you start adding in the accessories.
