Not to put down what these bulbs are, but I noticed there were no specs as far as light output which is usually expressed in lumens.
To say it's a % greater than standard bulbs is actually just a claim which we can't evaluate.
I also found out in my quest for better lighting that some bulbs are brighter but have a very short life which when you consider the cost is a huge downside.
I get annoyed by producers today with there claims of being better but no evidence is provided to back it up.
"New Improved" better than ever. I can't count the times I've seen that on some products in the last 40 years.
