No. Even proper pool light manufacturers have trouble making good underwater lights. Pressure from water can do amazing things to seals. If you are using something not intended for underwater use – dont mount it too deep in the pool. Ensure it is 12V or worst case 24V (12V is the legal standard here in Perth Western Australia now) 24V can potentially interfere with a pacemaker… Good pool lights can be found from companies such as spa electrics, poolrite and waterco and im sure all of these companies would send one to you in India. Retail for lights is around $240 plus a 100W 12v transformer for around $150 (outdoor model) All run on Halogen lamps – more advanced LED ones are available and so are retro fit models which easily replace old damaged lights.
