Energizer Double Bright, retail $12.99 (www.energizer.com...)

Last updated 08-11-09




The Energizer Double Bright is a plastic handheld flashlight that features a focused white LED in the end, and a CCFT (Cold Cathode Fluorescent Tube) on its top, allowing you to select either spot or flood as needed.

A rubbery material over the barrel helps you keep a grip on things; lessening the chance you might drop the Double Bright; turning it into a "Single Bright", or even worse, a "Double Dark".

It feeds from four AA cells, already included and installed.


SIZE



To use the Double Bright, remove it from its package, removing the short "Test Me" wire by sliding the battery door off and pulling the wire out. Reinstall the battery door, and then you'll be ready to roll.

Slide the switch on the top of the barrel forward to turn the white LED on. Slide the swich backward (toward the flashlight's tail) until it clicks once to turn the LED off.

Slide the switch backward until it clicks again to turn the CCFT on. Slide the switch forward (toward the LED-end) until it clicks to turn the CCFT off.

The center position of the switch is always off.

There is a legend silkscreened in white on the right side of the flashlight under the switch; this can help if you forget which is which.

You can stand the Double Bright up on its tail so the CCFT faces out where you need the light. You can also stand this light on its bezel, but it's considerably less stable this way because the bezel is tilted at a slight angle.



To change the batteries in your Double Bright, hold the flashlight sideways so the CCFT is facing up. Remove the battery door by pressing in on it slightly while sliding it down. When this door comes off, set it aside.

Remove the four dead AA cells from the flashlight, and dispose of or recycle them as you see fit.

Holding the Double Bright sideways like you did a moment ago, insert two new AA cells into the chamber, button-end (+) positive first. Insert two more new AA cells in the chamber above the first set, flat-end (-) negative first.
There is a polarity legend embossed into the right rear portion of the flashlight, so you can't screw it up too easily.

Turn the flashlight upright if desired, so the battery opening faces up. Slide the battery door on, pushing down on it slightly while sliding it in place until it fits flush with the rest of the flashlight.
There, all done now.

Current consumption differs depending on which light you use.
For the LED, it's 77mA. For the CCFT, it's 316mA.
The LED current seems high, but the CCFT current seems about right.

The Energizer Double Bright is *reasonably* durable, but it is not indestructible. It has a plastic body, and a glass tube in its side, so I'd better not try to throw it or smack it against a steel rod, because it would probably become broken and then I'd be {vulgar term for having had intercourse}.

The flashlight is lightly sprinkle- and splash-resistant, but it is not waterproof or submersible. The LED portion will probably still function if the insides got flooded, but do not under any circumstances try to use the CCFT if you know or suspect the Double Bright got flooded. This is because the Double Bright has a high voltage inverter to run its fluorescent tube; and as most of us know, high voltage and water do not mix. You might get zapped, and/or the flashlight's electronics might get fried if you try to use the CCFT while the Double Bright was flooded or otherwise wet inside.

If you know or suspect it got flooded inside, remove the battery door and batteries, shake out as much water as you can through the battery opening, and set it in a warm, dry place for at least a week to be sure its really dry inside before you reassemble and use it again. If it fell into seawater or if someone or something peed on it, douche the Double Bright out with fresh water and shake the water out before setting the flashlight out to dry.

If you flood the Double Bright and then fry it, I don't believe the warranty will cover that. It *might*, but I don't think it will.

The CCFT portion of the Double Bright appears to be about as bright as a 5 watt standard fluorescent light bulb; however since I do not have one to compare it with, please take this value with plenty of crystalline sodium chloride (plenty of grains of salt).
The CCFT needs approximately 20 to 30 seconds to "warm up" to its maximum intensity; allow this amount of time to pass first before deciding the batteries need to be replaced.



Beam photo of LED at ~12".
Measures 85,700mcd on a Meterman LM631 light meter.

Brightness is this high because the LED beam is focused into a medium
spot with a lens, and because the LED is significantly overdriven.

Yes, I collect those things too, along with used up old insulaters and all the damn flashlights. ;-)

TEST NOTES:
Sample was sent by a website fan along with three other flashlights, and was received late on the afternoon of 08-20-04.


UPDATE: 08-22-04
Unit costs somewhere between $9 and $13 at Target. The sender thinks it was approximately $10.


UPDATE: 08-24-04
The sender went back to Target to check the price, and it is $12.99.
Thank you for verifying that, and thank you for sending the Double Bright to begin with!!!

I also used the CCFT portion of the Double Bright to light up a windowless bathroom just after 8:30pm PDT, and it did just fine.
