Lan Lee gave me this link SD05 5000ºK w/out timed stepdown.
You did confirm what I suspected. The newer model is DD w/fet and has its downsides. But not having this timed throttling is a net gain.
I ordered last night - it’ll take some 8 to 12 weeks to get here. I have orders backed up since March.
One another note, Hank4U2 hank posted a discounted SD03 on AE link. $12 US.
Funtastic is looking into some 50 units, but I saw 60 down to 52 w/in a couple of hours.
