Mr 16 Led Light Bulb To Replace 50w Halogen Downlight

[cookcpu 1]

Anyone know which shop sell MR 16 LED light bulb. It is to replace 50w halogen downlight.

Any information given will be appreciated. Thank you.

Not so straightforward, as some old halo transformer may not work with the LED lightbulb.

The low Amp of the LED lightbulb may be below the operating current of the original halo transformer.

This shop got tons of experience to advise.

Thank you very much. I will go check it out and maybe buy one to test it.

Never! LED still has not reach a a stage whereby it could replace a 50W halogen in the MR16 bulb shape. However, there are a few good LED MR16 that could replace a 20-35W Halogen. Have to be careful though, to use a Magnetic Transformer instead of electronic transformer to light up these LED. Reason is LED wattage is too low for the electronic transformer to handle, and users may experience light flickering.

Good luck in your hunt!

Hi,

There is actually more than one kind of MR16! MR 16 actually refers to the diameter of the face of the typical MR16 halogen bulb : 1.6". There are actually two bases for MR16, GU5.3 (more common, 2 pins, requires transformer, 12V) or GU10 (less common, 2 "plugs", fits direct into mains, 220~240V). When switching to LED, the more reliable, energy saving option for MR16 may actually be the GU10. This is because GU5.3 requires an external transformer and these may not be very reliable - some transformers can not take the reduced load of LED thus continue drawing high current.

I actually bought some MR16, GU5.3 from one of the popular places for LED light bulbs but they don't work very well though they supposedly use Cree LEDs. Even though it is also advertised as dimmable (according to sales person), they did not work well with my existing dimmers. In terms of colour rendering, LEDs are acceptable, but some may not find it "warm" enough. Brightness is also a concern, I'm not sure that a 3W LED bulb can replace 50W halogen. I think it can probably go up to maybe 30W halogen.

Just thought I would share some of my experience when experimenting with this technology. I wonder whether reliable LED dimmable GU10s are readily available in Singapore.

Hi xmtan,

You can try Philips GU10 - 7Watt. It claims to be dimmable......coming from Philips, i trust it should be more reliable. But it's expensive also.....in the range of S$60-70 Each.

So far, my little experiment with LED is that a 3W can only just barely replace a 20W halogen.

Cheers

The GU10 that I am using cost me $100 per unit. I use it for corridor lighting and it replace the 50 w halogen bulb. There are 2 model one is warm light and the other is daylight. So far, I feel that the daylight model seem to be brighter.

Best you have to test every unit when you buy it. I got one that keep making noise after using for a while. I am still waiting for the cost to come down before buying more of it.

The Philips 7W GU10 LED can replace the 50W halogen bulb with quite similar coverage & Lux level, but due to the size of the bulb, not every type of halogen light fitting can be use, is dimmable but depend on the type of dimmer u r using. As for colour temperature of the LED is 3000K , same as the standard halogen bulb

Lightcraft has a range of LED lighting, i/c table lamps.

Got my wall lights from them. See them on my blog.

PS: LED T8 tube lights have made the scene, giving light as high as 2000 lumens !!! They will replace the common fluorescent tubes.

Sim Lim towers selling LED downlights below 100 buxs, there are quite a number of shops to check out too. They are at level 2 and 3.

The lighting shops charging an arm and leg for just 1 led downlight, can practically give them a miss for the time being.

Lightings.com.sg charges 3 mr 16 in 1 casing cost S$95. At sim lim towers at S$85.

The Daylight version for any type and brand of LED will always be brighter than the warm white by at least 20%. The noise you are experiencing actually comes from the dimming switch rather than the LED. Unless of course the electronic componets of the LED is of low quality and not suitable for standard dimming switches. Most standard buy-off-shelves dimming switches are using TRIAC Dimming or LEADING EDGE dimming methods, which is consider the "Lower end" type, and will work fine with halogens and incandescent but not all LED. For any type of dimming swtich, there is a min LOAD of at least 40-60Watts power.......LED wattage is too low for the dimming to handle, and thus flickering and noise may occur.

$100 for a GU10 LED Bulb? And you're willing to pay?

Do you have a showroom? Where can I get your LED products?

I think a led bulb can replace 50w halogen downlight. But it depends on how many leds a bulb contain.

The Lumen of 50w halogen is 560, and Lumen of a led is 160. 560/160=3.5 So a 3W led bulb can be as bright as a 50w halogen downlight.
