The invention provides an LED lamp with a high light effect. The LED lamp comprises a semi-transparent lampshade, a first LED luminescence lamp strip, a second LED luminescence lamp strip, a wire, a heat dissipation aluminum substrate, a power supply, a lamp holder and a mounting base; the upper end of the lamp holder is fixed with the semi-transparent lampshade in an internal and external threadscrewing mode, and the lower end of the lamp holder is fixed with the mounting base in an internal and external thread screwing mode; the power supply is detachably arranged in the lamp holder; and the heat dissipation aluminum substrate is arranged in the semi-transparent lampshade and installed at the power supply end. The LED lamp has the advantages that the structure is simple, luminescence ismore uniform, and the light effect is higher; and in long-term use, the lumen maintenance is better, and the color coordinate drift is less.
