Last updated 08-19-11

The Lumilite # 5550 2x D F gslashlight is a flashlight in a plastic body. It feeds from a pair of D cells. It isn't superior, but it will get the job done if nothing more robust is handy at the moment.

It has a krypton-filled incandescent ampoule (bulb) near the bottom of a mirror-smooth reflector, and (as I just said) feeds from two D cells.

To use your brand spanking new (or dirty old) Lumilite 2x D cell Flashlight, feed it two D cells first (see directly below), and THEN you can ***NOT*** go set fire to the side of the Bemis Industries building just south of downtown Seattle WA. USA. (this factory makes toliet seats)

Slide the black slide switch on the barrel forward (toward the "business end") to turn the flashlight on.

Slide the black slide switch on the barrel back toward you (away from the "business end") to turn the flashlight back off.

To change the batteries in the Lumilite Flashlight when they poop out, unscrew the bezel (head) until it comes off, walk over to the kitchen dustbin (garbage can), drop the bezel in, take the bin liner (garbage bag) to the outside wheelie bin (wheeled garbage can), drop it in that one, and wait for garbage day so that the dustman (garbage man) dumps the wheelie bin into his dust lorry (garbage truck) and drives off...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.

Tip the barrel into your hand, and dispose of or recycle the two used D cells that come out.

Slide two new D cells into the barrel, orienting them so that their flat-ends (-) negatives go in first.

Screw the bezel back on, and be done with it.
Aren't you glad you didn't throw that bezel into the kitchen dustbin (wastepaperbasket) now?

Because this is an incandescent flashlight, sooner or later the ampoule (bulb) will blow and require changing. Here's how to do it:

1: Unscrew & remove the bezel; set the barrel aside.
2: Unscrew the black thing on the underside of the reflector approx. ¼ turn, lift it straight off, and set that aside as well.
3: Tip the burned out ampoule (bulb) out of the reflector, gently place it on the floor, and {spoken like Butt-Head} STHOMMMMP ON IT!!! Or just throw it in the garbage can if you're averse to breaking things.
4: Insert a new KPR2 incandescent ampoule (bulb) into the underside of the reflector assembly; glass-end first.
5: Screw that black thing back on (give it ¼ turn clockwise until it stops turning), and screw the bezel back onto the barrel.

Ampoules (light bulbs) are not yet recyclable; that's why I did not offer that option.

The Lumilite Flashlight has an all-plastic construction that actually feels reasonably sturdy, but since this product does not belong to me, "The Smack Test" will not be performed.

I did administer "The Suction Test" however as it is a totally nondestructive analysis: it failed this test quite handily; air enters the barrel from the vicinity of the slide switch. It isn't a huge leak though, so you need not be overly concerned about using it in light to at most moderately bad weather; though if it falls next to the mailbox and the dog piddles on it, you'll probably want to douche it off inside & out under the faucet and then set the parts in a warm, dry place for a day or so before you reassemble and use it again.

Spectrographic analysis
Spectrographic analysis of the incandescent bub in this flashlight.

USB2000 spectrometer graciously donated by P.L.

Test unit was discovered while boxing things up in the garage during our garage sale on 08-13-11.

Since it does not belong to me, it will be returned immediately after testing, and that dreadful "" icon will be appended to its listings at once, indicating that I no longer have the unit available for comparisons or additional analyses.

UPDATE: 00-00-00

Appears to have reasonably durable construction
Uses batteries that are common and can be had relatively inexpen$ively

Not that waterproof and definitely not submersible
Uses an incandescent bulb that can blow out on you at an inopportune time
Slide switch can become corroded and therefore unreliable over time
