IMPORTANT UPDATE:
After some serious consideration, I’d advise against buying the Starry Light without taking into account its major design flaw and one other thing; the light can work well, but odds are that you will have trouble with the head screwing on. Tonight, the 3rd - yes, third - straight unit I got and resold was bad. Only, this one was so bad that not even the retaining ring could be fixed. The threads were not made well enough for even one round of use. The guy went to re-fasten the head after charging the batteries and couldn’t get it. I thought it would be a simple fix, but I have it ready now to send back to I.S. for replacement. Calvin responded fast to the situation, but be advised that this item is not without its problems.
So if you get one like this and the retaining ring issue isn’t the cause, then you’ll still have a working light, but the head will just press on and not screw down—which means it may or may not stay in place during normal use and will just pull right off.
I really love this light, but this is a besetting and serious design flaw to be made aware of.
Another smaller consideration:* Runtime test in high mode was completed yesterday by me. You are looking at 27:56 seconds of stable high brightness on good nimh cells. After that, the light provides an additional 10 minutes of fastly diminishing output (diminishing thereafter to nothing). This was with my best (and only worthwhile Energizer cells). The Eneloops test has not been done (yet), but of the 3 people I sold these units to, all ended up recharging them with merely sporadic use—same as my Energizers when they were using Eneloops. So you can expect no more than, say, 40 minutes on high (far from the claimed 2+ hours).
Mild flickering issue also found: This was, however, a one-time thing and I can’t get it to do it again. Just FYI.
