We compared two UV/LED nail lamps from the same maker: the SUNUV UV Led Nail Lamp SUN4 and the SUNUV LED UV Nail Lamp Smart 2.0 (SUN5).
What we looked at
LED count, curing speed, and price.
The verdict
If you want the SUN4 with a low-heat mode that gradually increases power to reduce curing pain, it's the pick at £33.99, though it costs £4.00 more. If you would rather pay less for the Smart 2.0 (SUN5) with a hands-free auto sensor and faster 30-second curing, it's the alternative at £29.99.
A £33.99 UV nail lamp with 36 LEDs and a low-heat curing mode.
A £29.99 UV nail lamp with an auto sensor and 30-second curing.
