Introduction: Bulk Fill resins are used as materials to replace tooth structure, being important to identify the resistance of these to different LED light lamps with their powers, so that they are able to withstand masticatory forces. Objective: To analyze the resistance of Bulk Fill resins, with light curing of LED light lamps of different powers, subjected to compressive forces. Methods: The research was an observational, cross-sectional, quantitative experimental design. The study population consisted of 30 cylindrical samples divided into three groups of 10 Bulk Fill resins light cured with 3M, Woodpecker and Valo lamps, placed in an acrylic matrix with an ISO 4049 measurement (6mmx6mm). The data obtained were subsequently analyzed and recorded in the SPSS V25 program. Results: The data obtained indicate that Group A 3M Lamp 1550 MW presented a compressive strength of 3496.3 N; Group B Woodpecker Lamp 1350 MW of 3496.3 N; Group C Valo Lamp 1250 MW of 2084.1 N. Group A was the one that presented a compressive strength of 3496.3 N; Group B Woodpecker Lamp 1350 MW of 3496.3 N; Group C Valo Lamp 1250 MW of 2084.1 N. Group A presented the highest compressive strength to the rest of the photocured resins at different powers. Conclusions: When comparing the compressive strengths of the Bulk Fill resins, which were subjected to three different light curing lamp powers, Group A - 3M Lamp had a higher compressive strength than the other sample groups; however, it was evidenced that all groups can reach strength values higher than 5000 N, in addition, it was defined that the ideal light curing intensity for Bulk Fill resins should be equal to or greater than 1000mw/cm2.
