David, et al,
While, I've had Sensi-Bulbs in all my
interior reading lights now for years, and have both an OGM LED Tri-Color / Anchor light combo at the masthead, and OGM LED port/starboard pullpit mounted Nav Lights.....
I also have had Dr. LED interior lights (not their Nav light inserts).....
And, DR. LED has suffered from two major problems:
1) Lack of LED quality control...
2) Lack of customer support....
Two things here to note.....
A) My personal bad experiences with Dr. LED lights....and
B) Many posts on the SSCA disc, boards parelleling the troubles that both David, and I, have had....
My personal experience with DR. LED lights are with interior 16-LED-cluster MR16
replacements....
I bought a half-dozen of these in 2007, and within a few weeks, 2 of them had failed almost completely (only 2-3 of the 16 LED's were still working), those 2 units went into a dumpster in
Gibraltar.....
Within the next few weeks, another two units had failed in the same way....and over the next few weeks the remaining ones failed as well...
(I did not have any large voltage flucuations....just you typical 12.5v in the morning to 14.4v in afternoon, from
solar charging...)
Multiple e-mails to Dr. LED went unanswered....BUT, since I'd purchased them thru a dealer (Hotwire Enterprizes), I contacted them....
John and Libby, said to send the remaining bad units to them, and they'd send them off to Dr. LED for replacement / refund....
I did this upon arriving back in the US, and I requested a refund....
And within the month, I had my credit card account credited in full (just for the units that I returned, since I had trash-canned the first couple that failed...)
While I have NO use at all for Dr. LED light, and have found their lack of customer support to be unfortunately about on par with most businesses these days.....totally useless......
I cannot say enough good things about John and Libby at Hotwire!!! They are tuly nice people, and recommend them highly.....
Do a search on the SSCA disc boards, and you'll find some more data from those that have had these (and other) troubles.....
Please be aware that not everyone has had troubles with these lights.....
It appears the lack of QC, combined with the emphasis on "low prices", along with lack of customer support, adds up to troubles for many using Dr. LED lights.....
I hope this helps...
John
