The problem I have had with LED Lumen rating is it seems overly optimistic. I did a little research and it seems most vendors rate them at maximum output for the specific LED not for the lamp assembly as they have configured the replacement LED lamp. If the replacement LED has 12 LED's with a maximum output of 20 lumens each, then they rate the bulb assembly as 12X20 or 240 lumens when it may actually be something significantly less than this.
I have tried 4 or 5 different LED lamp assemblies, most from China off ebay and have yet to find one that has the output of the 20w halogen. I am using some of them, but the DW complains constantly. My concern is primarily the heat the 20w halogens produce and the damage to the puck light fixtures from that heat.
The 10w halogens are easier to replace as LED equivalents seem more available, but the 20w halogen has been somewhat elusive for me.
