Q&A: SHOULD YOU OVER VOLT A LED MR16 BULB LIKE A HALOGEN BULB…?
Question by Mountain bike: Should you over volt a LED mr16 bulb like a halogen bulb…? I know a lot of people over volt 12v mr16 halogen bulbs to 14.4 to give them more white light rather than yellow, but what about a 12v mr16 LED bulb would you want to run that at 14.4 volts or could you get a clear bright white light out of it by running it at 12volts. Also same question about the Cree XLamp XR-E LED Bulb – 12V AC/DC, MR16 Base.

REPLACED HALOGEN BY LED, HOW TO PREVENT TRANSFORMER SHUTDOWN?
Hi, I replaced two 12V 20W halogen bulbs (wired in parallel) by two 3W 12V LEDs also in parallel. The problem is that the transformer (in a kitchen fume hood) seems to shut down when both LEDs are connect. It can take one but the two cause problems. I guess this might be caused by the very low resistances of the the 2 LEDs connected in parallel that short circuit the transformer?… How can I reduce this “short circuit” without causing significant voltage drop for the LEDs? I tried using them in series but they will not work because they will then each have half the required voltage. Of course the idea is o find a solution that will also not significantly interfere with the energy savings associated with the change of halogen by LED. Btw, the LEDs are MR16 and have their own tiny voltage regulator/stabilizer circuit (or whatever that is).
Thanks! Hi, the individual LEDs are not 12V but the MR16 bulb (each containing 3 LED chips) is rated for 12V AC or DC. It has, as I mentioned, it’s own voltage regulator built in. The spots work well with one or two halogen lamps or just one LED (either one, so they both work fine). When both are connected then all blinks briefly and goes black.

ARE MR16 LED BULBS DIMMABLE?
I run a restaurant which is full of mr16 halogen bulbs which is eating up my electricity usage. I am planning on replacing them all with mr16 LED bulbs, but I have a question. Are all mr16 LED bulbs dimmable?

WHAT TYPE OF LIGHTING IS SAFEST FOR A HIGH-HEAT APPLICATION?
Trying to install accent lighting under a fireplace mantle, which obviously gets hot when there is a fire. Halogen bulbs are a no-no – killed the bulbs after 2 hours the first time the fireplace was on. Will LED bulbs be safe in this application? If so, should I buy a pre-integrated puck, or a fixture for MR16 or Gu10 lights? And which of those two options would be safer. MR16 means the transformer would be elsewhere, but it’d end up inside the wall or directly behind the plasma TV, so I am not sure that is any superior – Gu10s would have the transformer right at the light, but can they handle the light?
AC-LED’S APPLICATION? & THE OBSTACLE OF MR16 LIGHTING MARKET?
In which fields that AC-LED can apply?
Also, I want to know MR16 lighting market. What is its weakness and treat in this market?
12V AC/DC MR16 LED RETROFIT LANDSCAPE LIGHTING WILL I INPROVE SYSTEM BY DECRESING MY VOLTAGE DROP?
in long run with a larg number lights i want add more fixtures to existing system without add another circuit and transformer by useing led mr16 bulbs
IS THERE AN INEXPENSIVE WAY TO MAKE MY MR16 LED LIGHTS FLICKER?
Is there an affordable way to make my MR16 LED lights flicker at a fast rate like 400 to 600 times a min? I’m not even sure where to begin looking or what exactly to look for. Are there plans out there to build such a device? Can I buy something that will do it off the shelf for less than I can make it? Thanks in advance for your help
