The Unilite CRI-3250 is a high CRI site light that is part of their range of CRI rechargeable LED Site lights, and has the ability to be either mains powered or use the built-in rechargeable battery as well as offering a 2 A power bank output.
It has a variable output with a maximum of 3250 lumens on the highest setting and a minimum of 200 lumens on the lowest setting from a 30 W COB LED, as well as a variable colour temperatures between 2700 K and 6500 K.
Colour rendering index (CRI) is a measurement of a light sources ability to faithfully reveal the true colour of an object in comparison to a natural light source such as sunlight and is measured between 0-100. The CRI-3250 has a high CRI 96+ value, which means the quality of the light source is extremely good and shows colours in their true form and also helps reduce eye strain that lower CRI lights can cause.
Offering excellent light spread and power the CRI-3250 features two twist switches on the back to control all the settings. The left button is the on/off button and controls the brightness output by twisting the switch to the right to gradually increase the output to set it at your desired level, and will click when it turns on/off. The right CCT switch changes the colour temperature by twisting the switch to the left for warmer white light or to the right for cooler white light. When it is turned on the battery level indicator will light up to show remaining power.
Utilising a 11.1 V 5200 mAh lithium-ion rechargeable battery, the CRI-3250 has a run time of up to 2 hours on the highest setting. The battery is easily recharged by lifting the dust cover on the back of the light and inserting the charging cable into the charging port at one end and inserting the other end into the mains socket. The included mains adaptor comes with four different plug attachments for use in multiple countries such as UK, USA, Australia and in the EU. The light can also be used continuously whilst connected to the mains, even with a fully charged battery, which allows you to save the battery power if access to a mains socket is available when using the light.
While charging the charging indicators on the back will display charging progress with one light flashing to start with before becoming solid and the next light flashing until eventually all LEDs are solid after approximately 4 hours full charge time. In addition to the light function, the CRI-3250 also has a 2 A power bank feature and can charge external devices via the standard USB-A port located next to the charging port on the back. To charge an external device simply plug the USB-A end of the required cable for your device into the USB-A port on the light and the device should begin charging automatically.
It is made from a super tough nylon and aluminium construction, with a fluorescent yellow centre and also features a a glow in the dark strip around the reflector for increased visibility.
A stand is tucked away at the back and can be pulled out and rotated within a 170° range so that the light can be angled in the perfect direction and it also doubles as a strong magnet to attach to magnetic surfaces for hands free work. A handle allows for easy transportation of the light unit.
