LED MR16 vs Halogen MR16 Light Bulbs

- Another comparison video from www.illustralighting.com this time comparing an LED MR16 to its halogen counterpart. Every aspect of an MR16, as well as the advantages of LED over halogen, is clearly explained.

A very common remark. Basically when LED mr16 came out to replace the halogen version - they were about 5W and 250 lumens. They were (incorrectly) touted to replace a 50W halogen mr16. But they didn't have the light output to do the job.
(A fairer replacement would be for a 20W halogen)
You basically need about 500 led lumens to replace a 50W halogen, and these days you'll find that in an led mr16 of between 5W - 10W (depending on how efficient the led bulb is)
Hope that helps
Another way to look a this is that LEDs allows to increase light output without increasing heat. A 5W appears to be similar brightness than a 28W "eco halogen" and they are actually rated at 380 lm. I have some ceiling lights hanging down from plastic originally 20W, and the illumination increased signficantly with a mixture of 28/5. The selection of 12 Volt lamps available locally is limited, and they're cheaply made. I wonder if it is any harder to build than a 230Volt GU10, despite not needing to step down the voltage.
The uneven glass in your lamp probably helps to diffuse the light. Philips doesn't have that and casts 4 sharp shadows from each LED.
What about dimmable use. I have purchased various 'dimmable' LEDs for a variety of bulbs which simply did not work.
Any suggestions about where I might get MR16 lamps of >100lm/W ?
Great video and explanation.
A few months ago I replaced three 12V MR16 halogen spots with LED. What I did not know, and which is not explained in this video, is that if you use 12V bulbs the transformer has to be of the right type, or you will, like me, have your LED's burn out in a few months. So needless to say, I won't be replacing any more 12V halogen bulbs with LED unless I can replace the transformer as well.
Correct, Unfortunalty most modern "transformers" are switch mode power supplies, and these have a few issues with LED compatibility.
1. They require a minimum loading, typically 20W, and an LED is max 6-7W.
2. The resistive properties of the halogen lamp are quire often used as part of the transformers circuitry to smooth out the output from it, you may find that even if the do work, they flicker, and even if they dont, life will be reduced..
3. halogen lamps can cope with a "dirty" power feed, its not noticable, LEDs need it to be clean and stable
Thanks for the warning....is there anyway around replacing the transformer to be able to use the LED?
Yes, you can buy led drivers to replace the transformers. Most people just convert to gu10 where possible as there is a greater selection of retrofit gu10 lamps compared to 12v mr16s
Good informative infomercial - many thanks.
excellent video, good information
This doesn't show the feature of halogen MR16s that my light fixtures depend on, namely that light escapes through the back side of the reflector. That escaping light is what illuminates my pendant lights. All the LEDs I've found don't aim any light back toward the pendant, so I'd end up with dark pendants that look ugly. I need an LED replacement that looks nice!
I have the same issue with most LED MR16 replacements. I have found that if you need a MR16 GU10 bulb, this FEIT one has a decent amount of backlight MR16IFGU10500/5K/LED www.feit.com/product/500-lumens-5000k-mr16-dimmable-led-3/ I do wish it had still a bit more backscater though. As for an MR16 GU5.3 I have not found any that I think are worthy yet. I generally love FEIT bulbs, they have very pleasing lenses. This BPBAB/950CA one here has a tiny bit of backlight, but not really a worthy amount: www.feit.com/product/200-lumen-5000k-dimmable-led/ It would love to find a better halogen replacement, my bulbs are all burning out and I don't really want to put in more halogens.
i thought you were going to actually demonstrate the light of each
+dan428 Same.. all this does is tell us what we basically could have read anywhere.. what's the point of a video without a demo of the light real-world performance.
What about light quality? CRI for example........
Halogen MR16 may not last as long as the LED. Halogen MR16 50 watt beats the LED in Lumen big time. I have not yet found a LED MR16 that can beat the Halogen MR16 in Lumen.
romko5962 Yeah that's what he forgot to mention. Thanks for mentioning that.
Good information
Thank you
Attention people!
You can't change from halogen to LED MR16 because they work in different currents.
Halogen need DC transformer and LED need AC transformer.
Temporally it work but after few hours it burn the LED lamp.
From 50 000 h you may use it only 30-50 h.
Advantage is only to by a new system of light with LED MR16 LB.
+Rozafati If the system is 12V both would work the same.

You're about as bright as a burned out halogen bulb.
Thank you Rozafati. You confirmed my concern to change over to LED from Halogen.

He is WRONG. I have been running my leds in what was a halogen fixture for two years
Thank you for your comment. Though I am not an electrical engineer but will look into more details of how these two types of lights function/operate.
Halogen MR16 has a superior brightness and the "crispiness" of the light cannot be matched by LED, as I seen so far.
good!
The video suggests that these two bulbs are interchangeable. I don't think that's accurate
I don't like led lightbulb
