{"product_id":"g436-ho-li-master-copy","title":"G436\/HO-Li - 4pin High Output 436mm - Master","description":"\u003cp\u003eThe G436\/HO-Li is a 4-pin, 436mm high output replacement UV lamp compatible with the SITA UV 405 AL, LCD and LCD+ systems, as well as the GER25XOSE DaRo Saphir 3. WrekinWater stocks it as the correct annual replacement for these higher-output units, distinct from the standard-output lamps used elsewhere in the range. Getting the right output rating matters, since a standard lamp fitted to a high-output housing won't deliver the dose the system was designed around.\u003c\/p\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLamp code\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eG436\/HO-Li\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh output, 4-pin, 436mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible with\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSITA UV 405 AL \/ LCD \/ LCD+, GER25XOSE DaRo Saphir 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecommended replacement interval\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEvery 12 months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVendor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWrekinWater\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eG436\/HO-Li\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eSigns you need this part\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIt's roughly 12 months since the lamp was last replaced.\u003c\/li\u003e\n\u003cli\u003eYour system's monitor, where fitted, shows reduced UV output.\u003c\/li\u003e\n\u003cli\u003eThe lamp still illuminates but you can't verify whether it's still dosing correctly.\u003c\/li\u003e\n\u003cli\u003eWater taste, smell or clarity has changed even though the lamp appears to be working.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHigh output lamps are built to deliver a stronger UV dose than standard lamps, which is why systems like the SITA UV 405 and DaRo Saphir 3 are designed specifically around them. Like any UV lamp, output falls steadily over time long before the lamp fails to strike, so a lamp running past its 12-month interval may be under-dosing the water even though it still lights normally. Fitting the wrong lamp, or an old one, undermines the higher disinfection capability these systems were bought for in the first place.\u003c\/p\u003e\n\u003cp\u003eWrekinWater is a family-run water treatment specialist based in Bettisfield, Shropshire, with 15 years' experience and more than 50,000 customers served, rated Excellent on Trustpilot.
