Personally I think 3 seconds would be a bit fast, 4 seconds seems about right (Sofirn SP32A)
.
My TK18 takes about 7.5 seconds L to H (purchased @ amazon Jan 10)
The long ramp time may appeal to some users as it allows you to more precisely select your desired level.
For this light I prefer the 4-level (set mode) group, but I’m not a big fan of the reversing circle, takes some getting used to I guess.
I got the code, went to the page, only option was “preorder” vs “add to cart” or anything, and after clicking, it just went to an empty cart, nothing inside, no “we got youre pre-order”, nuttin’.
No, I went through the “pre-order” option and and was led through the payment sequence in the usual fashion. A little different for me probably because I had to open an account with Banggood—never shopped with them before. That was quick and easy and I payed through Paypal. Done deal. Got the order confirmation. It’ll be awhile but I reckon I can scratch by with the lights I have now.
