A differenza di altre reattanze similari queste oltre a coprire un wattaggio da 39 a 55 Watt ha anche un fusibile di sicurezza integrato nella presa (che è ti tipo UK non italiana ma ha insieme un ottimo adattatore per farla diventare una normale shuko quindi nessun problema). Al momento mi sento di consigliare i prodotti della realgoal per l'ottima qualità ed il giusto prezzo. Se quanto scritto ti è utile ti prego di farmelo sapere. Review: Took a chance on buying this ballast to fit a 55w uv light. It was perfect. The cover for the end of the uv unit didn't fit but it's a different brand so my own fault. Very reasonable and I'm very happy ## Features - input : 220-240V 50/60Hz - output current: 425mA - power；40W-55W - With Led and Sound Alarm ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Realgoal | | Model Number | UV BALLAST 40-55W/US | | Color | Replacement ballast 55w | | Product Dimensions | 13.92 x 8.64 x 10.41 cm; 322.05 g | | Power / Wattage | 55 watts | | Material | Plastic | | Special Features | LED and Sound Alarm | | Item Weight | 322 g | ## Product Details - **Brand:** Realgoal - **Special features:** LED and Sound Alarm - **Wattage:** 55 watts - **Material:** Plastic - **Model name:** UV BALLAST ## Images ![Replacement 40W-55W Electrical Ballast - Image 1](https://m.media-amazon.com/images/I/615dEWL3fTL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Will this work on a alpine corporation uv light?** A: Hello, this uv ballast is only fit for the lamp type single end 4 pins.
