277VAC 12VDC 30W dimmable electronic transformer small size
The 12v small led transformer is compatible well with the led bulb is not included in the package. With an E26 sized screw base, the bulb can be installed as desired. To get a better lighting effect, we suggest you using LED bulb 10W-12W, energy saving bulb 12W-20W.

Notes |
1. All parameters NOT specially mentioned are measured at 120VAC input , rated load and 25℃of ambient temperature. 2. Tolerance: includes set up tolerance, line regulation and load regulation . 3. The power supply is considered as a component that will be operated in combination with final Equipment. Since EMC performance will be affected by the complete installation, the final equipment manufactures must be-qualify EMC Directive on the complete installation again. |
