- Radii-cal high powered cordless LED curing light is light on weight, radically powerful. - Unlike many other LED lights, the Radii-cal does not require a fan. - Ramp-up mode: During the first 5 seconds, the Radii-cal’s light output power gradually increases. - This soft-start polymerization minimizes stress at the restoration-enamel/dentin junction and reduces marginal gaps in the restoration. - A fully charged Radii-cal allows you 720 ten-second cures before you need to recharge again. - The battery pack simply unscrews from the Radii-Cal unit and can be replaced. **For further product information, please contact Chat Support**
