    So I finally got some of the Kumho LED lamps so I figured this would be a good time to do a side by side comparison. I have seen the Ushio LED in action at Light Fair, in all fairness the one I saw at LFI is a warmer LED vs. the one they gave me which is much cooler in temp. I believe the one I have is 4500K or what USHIO calls their Neutral White. They make a few in 3200K which is what I saw at the show and was really nice and close to the BAB they had next to it.

    I am not sure what the Kelvin temp is on the Kumho the BAB has a Kelvin temp of 2950.

    Here is a side by side of all 3. They were placed in Nova fixtures, the Kumho has the angle shroud on it. In this picture they are shining on a TAN painted wall. Left To Right: USHIo LED, KUMHO, USHIO BAB.

    These next pictures I took to show the output as best as I could.

    IMHO neither the Kumho or Ushio LED's come close in color or output. They are good but not even close. The camera really doesnt show how much brighter the 20w BAB really is. I will say the Kumho is really nice in terms of beam pattern. The other 2 lamps both have a lot of stirations in the beam.

    I will leave the rest up to you guys to decide.

    one thing I imediatly notice is the cleaner output. Sometimes I wonder WHY we are all so set on EXACTLY recreating the halogen color. A full matching job done in something a little bit different in color could look pretty nice in my opinion.

    Thanks for the comparison Joey.

    Also didnt ushio have 2 different led's on display ? I think the warmer one we are thinking about was all the was down to the left of thier wall wasnt it ? Which model Kumho is this ?

    Thanks for the demonstration Joey. I won't be running out and buying LEDs any time soon. An extra 5-10 bucks a month for my customers power bill isn't going to break their bank by using the better looking and more powerful halogens.

    I just completed an addition to a system that I originally installed in 2006. I added a comprenensive zone of tree mounted downlights over granite flagstone paths and patios. This time around I used 100% LED MR16s, 4.3W, 60 Deg, Warm White (3100K).

    I was out last night to aim the system. We had trouble identifying the difference between the zone that was installed with GE BABs + Optical Spread Lenses (I had been lensing almost 100% of my downlights in the past couple of years as I find the BAB to be just too bright in most applications) and the zone that used the Kumho LED Lamps. I kid you not... the only difference was there were no visible abberations in the light pattern from the LEDs.

    Shining the beams up against a wall might not be the best way to compare the effectiveness of their output, but I appreciate all of the effort and time Joey.

    Have a great day.

    I also notice quite a difference in the lumens output between the LED MR16s and the halogens. I am putting together the same type of experiment with the Kichler LED lights and will be sure to post pics of that.

    Thanks Joey!

    Billy, This LED I used is not the warm white 3200K that was on the far left of Ushios booth. That lamp was much nicer in color rendition then the sample I had to use in this test. That one was much better than the Neutral WHite 4500K I demonstrated. Both say they are equivelant in output to a 20w BAB. This lamp is 34deg where the BAB is a 36deg. The Kumho I used here is the Warm White 3w which says on the box is equivelant to the MR16 20w MAX 240Lm.

    Again photos rarely do lighting justice but as for the color rendition. The BAB is theonly lamp that showed the true color of the wall. The others changd the color of the wall and ceiling quite a bit. We shined some onto a wood surface and you could really see how the LED's turned it grey almost in color vs. the BAB which showed its true color.

    Although they are getting better and closer, for the cost of these lamps (LED) I am not sure they are worth it at this point. But like I said I was very impressed with the smoothness of the LED vs. the BAB when it came to beam pattern and spread.

    If you really want to test these lamps out then you have to install them in a system and look for yourself. Here at my home my wife cannot see a difference, at a very large jobsite the client cannot see the difference and 1/2 of his property is Halogen and 1/2 LED and he is a very discriminating and particular person.

    Testing them up against a wall or door with the object located only a couple of feet away from the source doesn't really tell the whole story.

    Also, very subtle differences in colour temperature, beam spread and even intensity are lost in most outdoor applications. When an entire project is lit with the same lamp, there is going to be no comparisons made.

    Pick up some of the Kumho, Ushio, and Lamina LED MR16s for yourself and install them in your own lighting system as a test. Then you will see first hand what I am talking about.

    Next... the arrival of the 35W equivalent from Canadian manufacturer CRS Electronics...

    Yet some of us strive to eliminate these differences. Against a tree, or coming down out of a tree, this might not be an issue. Against the columns of a grand entrance to a 12 million dollar home these color differences are crucial. It's the difference in being "remarkable" or just settling for what will work for your own personal gain. :hammerhead:

    Sorry- but you guys are installing lights every day with different color light and different color rendition. a 20 watt halogen mr-16 at 10.5 volts has a way different color and relative brightness than a 20 watt one at 11.5. were you to hold them each up to a tan or white wall the difference would be obvious.

    With LED, it is my understanding they are a constant color and brightness whether at 10 or 13 volts. The very discerning eye may not like that color, and I'll accept that, but to my eye above the LED's look to wash the wall better and not have a hotspot. I like the color and lumens better on the halogen, but the LED's are close, much closer than they were just 18 months ago.

    You are correct, but you won't find that kind of difference in voltage drop in one of my systems. Especially when it comes to columns.
