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. USHIO LED on White background KUMHO LED on White background USHIO BAB Halogen on White background USHIO LED on Tan background KUMHO LED on Tan background USHIO BAB Halogen on Tan background These next pictures I took to show the output as best as I could. USHIO LED KUMHO LED USHIO 20w BAB Halogen 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.
