Efficiency of 219B vs 219A

etc · Oct 1, 2017

I just got M61LLL 219B and the tint is certainly very nice.

Question, are there any runtime improvements in the 219B module? I was under the impression the original 219 wasn't all that efficient, even in the M61LLL configuration.

219B is a newer generation than 219A so it is more efficient.

Just a wild guess but if the driver is the same maybe the difference would be increased output not long run times.

I shined both side by side , a 'white wall test', aside from the tint improvements, I cannot quantify any difference. I haven't really tested for runtime, which is not easy to do given how long they run.
