Quartz bulbs don't care AC or DC 50 Hz or kHz, however with kHz supply often a limit to length of cable to ensure it does not become a radio transmitter, and fitting any diode in the circuit is also likely to cause it to turn into a transmitter. DPO2012B oscilloscope. A sample of LED lights was used on each transformer to assess it's compatibility and output LED (light-emitting diode) light bulbs are the most technologically advanced and energy-efficient bulbs available. They last many times longer than halogen light bulbs, produce the same amount of light, but use only a fraction of the energy. Most LED light bulbs can be used with existing light fittings (this is called retrofitting). Different LED drivers are required for different environments for example indoor, outdoor use or kitchen or bathroom. If the driver is to be used outside we recommend that a waterproof driver is used with a minimim IP 65 rating. We would also recomend this for kitchens and bathrooms a waterproof driver with a IP67 minimum rating is used.Not entirely accurate as in greece and eastern europe you can get mr16 fitting spots that use 230v and can be replaced with mr16 230v leds. The high frequency switching cycles are seen to stop and resume at irregular times within the 100 Hz wave envelope. Often extra low voltage (12 volt) is wired with twin core, it says "A circuit protective conductor shall be run to and terminated at each point in wiring and at each accessory except a lampholder having no exposed-conductive-parts and suspended from such a point." in the main MR16 lamps are not suspended so need and earth taking to lamp even if not used.

Fortunately, upgrading Halogen MR16 light bulbs to LED is usually a painless affair, as most LED light bulbs are now designed to retrofit to existing light fittings. All you have to do to swap your old bulbs out is remove them from the light fixture and fit the new, shiny bulbs in their place. You state : “The reason for this is that they need a minimum voltage to pass through them to operate “. I believe you mean “load” to pass through them. It is the load that causes the issue when it is not large enough to fully turn on the circuit.identical loads varied greatly, however while power losses do tend to increase with an increase in switching to their D900 Curve LED downlight. The voltage is approximately 36.5V (oscillating slightly on account of voltage ripple from the 50 Hz mains) DC. If you want to upgrade these older bulbs to MR16 smart light bulbs, Philips Hue has the answer. The new MR16 smart bulb is the ideal solution for your existing MR16 fittings. They work on the same 12 V low voltage as standard MR16 bulbs — so you won’t have to remove or replace your existing transformer. You can see which transformers Philips Hue smart MR16 bulbs are compatible with here. I'd place the transformer centrally to keep the LV cable runs short - the longest would need to be about 1.5m. Driver should refer to a current regulated DC power supply, but often same name given to voltage regulated device, so you need to be careful.

The volt-ampere (VA) rating is the maximum load (in watts) that a transformer can safely carry. For example, a 40VA transformer can handle up to 40-watts of electrical equipment, while a 10-60VA one can carry between 10 and 60 watts worth. Installing low voltage LED light bulbs on a transformer designed for halogen lighting requires you to find the equivalent wattage ( see above) for the LED bulbs, so as not to overload the transformer. i’ve tried replacing my warm led spotlights with brighter led spotlights but they flash on and then go super dim. Can you help explain why that might be? You can now get dimmable G4’s in 220VAC & 12VDC. This asks the question… is its best to swap the driver and use 12V LED’s or by-pass the original transformer and use 220V LED’s? I converted all my light fittings in my old house to LED’s & noticed HUGE savings! I actually only did it to boost my home energy report.. The first number gives the protection level against solid objects from 0-6 with 6 the best protection (i.e. no dust or anything would enter the device).Not sure if your still thinking of changing to LED's but These are the mains voltage equivalent of MR16 GU, which stands for “general use”, refers to the base, or fitting, of the bulb. The number after GU refers to the spacing between the pins. GU10 has 10 mm spacing, while GU5.3 has 5.3 mm spacing.
