Im a paid and waitin customer for the hds high cri, and the to follow 2 aa battery tube..
I went to led because you never have to replace them, (do many people remember Incan BULBS? drop your light, and oops, time to replace, if you have the right one..I gathered a collection of old bulbs in a lure box, so I'd never be without..then the batteries would die...)
And now you guys replace the "bulbs" more often than I did! oh the irony.
The next step, now that the bulbs last forever, obviously, is to never need to replace, or charge, the batteries!
