Introduction: Bond strength is an important property and determines the amount of force delivered treatment duration in orthodontics. Many light-cured bonding materials are being used; but it required to determine most efficient one withdesired bond strength.
 Objective: To compare shear three visible composites (Transbond XT, Heliositand Enlight) two self-cured (Rely-a-bond Concise).
 Materials & Method: 100 extracted premolars were collected randomly divided into 5 test groups different adhesives. Brackets bonded teeth each group with respective adhesive according manufacturer’s instructions. Each specimen was debonded using Universal Testing Machine for calculated. All compared by ANOVA one-way test.
 Results: There statistically significant differences among five (P<0.05). The Enlight (13.92 ± 3.92) similar Transbond XT (14.30 4.35).
 Conclusion: Light cure showed higher than self composites.
