It steps the mains supply down to 12 V through a galvanically isolated winding, so no mains potential can reach the water even if a lamp seal fails — the arrangement required by pool-lighting safety practice. 200 W carries five 36 W lamps or eleven 18 W lamps at the arithmetic limit; specify to about 80 per cent of the rating for margin, so four 36 W or ten 18 W lamps per unit. Add the lamp wattages and divide by 200, rounding up, to get the number of transformers. Install in a dry, ventilated enclosure at the distance from the pool edge that local electrical rules require, and protect the primary side with an RCD.\u003c\/p\u003e\n\u003cp class=\"ws-avail\"\u003e\u003cstrong\u003eRef.\u003c\/strong\u003e T-1-300 · Ships within 14 days\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"ws-table ws-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRated power\u003c\/th\u003e\n\u003ctd\u003e200 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eInput\u003c\/th\u003e\n\u003ctd\u003e220 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCasing\u003c\/th\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eOutput\u003c\/th\u003e\n\u003ctd\u003e12–14 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eUnderwater lighting in pools, fountains and spas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp class=\"ws-datasheet\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0794\/7835\/8235\/files\/Waterstar_Datasheet_Safety_Transformer_v02_2026-10-19.pdf\" target=\"_blank\" rel=\"noopener\"\u003eDownload the technical datasheet (PDF)\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Waterstar","offers":[{"title":"Default Title","offer_id":50660391190747,"sku":"T-1-300","price":2593.5,"currency_code":"EGP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/7835\/8235\/files\/transformer.jpg?v=1792335405"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/7835\/8235\/collections\/ws-coll-transformers.jpg?v=1792059934","url":"https:\/\/shop.waterstarpools.com\/collections\/transformers.oembed","provider":"Waterstar","version":"1.0","type":"link"}
