Guess the reason is that the Nichia is 200lm and the Samsung is 300lm. Explanation with example: One percent of $300 is also more than one percent of $200, both it is 1% but absolutely 1% of $300 is more.
The reason must be something else, there may be a difference in beam profile and lux due to different diode sizes, or a really different level, as some NLTs had a very low 1 level.
For everything should have 0.02 lm
