Is the LED/UV lamp included in starter kits strong enough?

Reviewers on r/DIYGelNails and r/Nailtechs caution that some bundled lamps undercure thicker or darker gels, even when the box says 60 seconds is enough. A safer approach reported by community users is to double the cure time, or pair budget polishes with a known-good 48W+ dual-wavelength lamp from a brand like MelodySusie or SunUV.
