15 best lighting emergency lights

Product description

Compiled from over 1,000 hours of tapes, The Golden Road presents remastered and (except for Live Dead ) EXPANDED versions of all their Warner Bros. albums, all with digipak packaging featuring additional 16-page booklets authored by everybody from Lenny Kaye to Owsley, plus a 2-CD set (one live, one studio) presenting unreleased performances from their pre-Warner Bros. days. An 80-page accompanies. The sum total: 8 CDs, over 15*1/2* hours of music, seven hours of unreleased material!

Considering the amount of posthumous product released since Jerry Garcia and the Grateful Dead's demise in 1995, perhaps a better name for the band would be the Living Dead. However, there is no denying the fact that the Dead's music--at various times thrilling, adventurous, simple, futuristic, old-fashioned, ethereal, abominable, ridiculous, and sublime--bears this kind of deep exploration. Rhino's 12-disc bonanza is the definitive look at the Dead's formative years, a fantastically creative nine-year period for Warner Bros. In 1965, they were a bunch of ex-folk and bluegrass musicians who were looking to jump on the rock bandwagon driven by the Beatles. The ensuing decade found them travel a sort of circular path that began with revved-up renditions of their folk and blues favorites. Then they maneuvered through intense, far-reaching, mind-blowing psychedelic experiments, settled into timeless stripped-down Americana, and ended atop a mountain where folk, blues, country, jazz, and psychedelic rock lived in near-perfect harmony.

All of the band's nine official Warner releases (five studio discs, four live) have been superbly remastered and buffed with extra tracks that include unheard studio jams and outtakes, plus contemporaneous live cuts. There's also two discs' worth (one studio, one live) of rare early material that predates their Warner Bros. debut. Each "album" comes in its own package with its own notes, while the box itself offers a 75-page booklet filled with thoughtful essays, personal reflections, and great photos. Clearly, Rhino has thrown down the gauntlet to Deadheads everywhere: they know you have most of this stuff in a variety of forms, but with the bounty of bonus tracks, the superior sound, and the wonderful packaging it's as if they're issuing a challenge not to buy this exquisite collection. --Marc Greilsamer

User questions & answers

Question:	can i connect this to a 12 volt power source to energize when the 12 volt power source fails
Answer:	I believe when they Identified this as a AC/DC Power source they are speaking of the Rechargable Battery Back up as the DC Power source. Battery back up is Usually no more than 3volt, My guess is if you add 12 volt to it , You would be shorting out the Rechargeable part of it. In Short, I would not Add 12 volt to it.

User questions & answers

Question:	How far apart in feet you can install this EG light in a corridor/hallway of 6 feet wide
Answer:	It may be out of memory? I never use the phone connection feature anymore since it is buggy. Probably a software update on the phone that is incompatible with the wiretap. Perhaps there is a firmware update available for wiretap? The only problem I have with this pedal is the playback volume being so much louder than the original input signal was. Hope this helps.
Question:	How many lumens are these each bulb and each unit
Answer:	You cannot import audio files. However, you can record any audio source via the ¼” mono input jack. We are your TC Authorized dealer with full warranty and support, any other questions please let us know.
Question:	Do these lights have only a single aa battery as stated or is it a 3.6 volt aa battery pack
Answer:	I have not tried this. You may be able to use a microphone and connect it to the input of the Wiretap. But it was designed to receive input from a guitar, so I do not know what the quality would be. You may want to read some of the forums where they discuss the wire tap and see if anyone has tried it.
Question:	Do they go off on own when power comes back on
Answer:	NO, it does not come with a power supply.

User questions & answers

Question:	where can a new battery be purchased
Answer:	I would try on line search or Batteries Plus. Some times the battery cost as much as a new light.
Question:	Why can't it be mounted on the ceiling in my basement since I do not need exit signs
Answer:	I don't recall seeing a ceiling-mount rating on them. All electrical fixtures are rated for wall or ceiling mount or sometimes both ways. A electrical fixture is constructed taking it's approved use in consideration. This emergency light has 4 plastic clips that are not designed to hold the vertical weight that could fall on someone's head. Using a wall-mounted fixture on a ceiling can also overheat the building's wires.
Question:	Please somebody help me! how is this connected to my house power??? i want a plug-in device. thanks
Answer:	Amazon just sent me your question. I installed this emergency light at church about 2 weeks ago. You do need a 110 volt AC junction box to connect the light's wires to your home electrical system. If you do not have a junction box with wire from your circuit breaker box, the cost of an electrician to do tis for you many not be worth that added expense.
Question:	How many 1-aa lithium single batteries in this fixture or must they be bought in an expensive bundle to be used in this fixture
Answer:	The batteries in my units were Ni-cad, three AA bundled to total 3.6V
