FAQ

• Will this fit my fixture?
  Only if your fixture is 12V low-voltage with a compatible transformer and takes a GU5.3 MR16 reflector — check your old bulb's base and voltage before ordering.
• Do I need a transformer?
  Yes, this is a 12V bulb and needs a 12V transformer; it will not run on 230V mains directly.
• What's the difference between this and a narrow-spot MR16?
  This is a wide 36° flood beam for even, general-purpose lighting; a narrow-spot version throws a tighter, more focused beam better suited to highlighting a single object.
• How long will this halogen bulb last?
  Rated life varies by exact Osram variant; ask our team to confirm the current batch's rated hours before a large order.
