electronic-101 for the dutch

[flyingdutch]

...cos the Dutch somehow managed to get straight-A's in highschoo
maths-n-sciences but filed it in the "I'll never use this ****e in rea
life" part of the brain... :rolleyes:

Recently one of the globes blew/broke/she_no_go on my rusty Catey
Daylights

Normally runs (from rechargeable battery that can get me 3.5-4 commut
rides, 1 hour each-ish) 6W-6V and brighter 10W-6V Halogens

LBS could only get me a 2.4W-6V globe which seems not as bright bu
they assured me it will run longer (well it damn well should seeing a
how much dimmer the light is!)

My question to you Electrical Engineers out there is, apart from th
current 10Watter, what is the ideal/alternative setup i can run an
where is the best place to get these wonders?
(i tried Jaycar but they dont do any 6V halogen type things :( )

See? the proppelorheads' presence on aus.bicycle is indeed a goo
thing. Now, earn your keep and enlighten me :D

fanx in advance

http://www.reflectalite.com/index.html is the ultimate listing
of bicycle-type bulbs. They're in the UK, but you can post
them a personal cheque in Aussie dollars, and they'll post the
goods back. Or you can use PayPal.

well, the numbers seem right on that last option but my current globe
are just lil' bayonet fitting (without the bayonets, if your wit
me...) that sit in a housing inside a screw on lense. not dissimilar t
a torch style arrangement

Cateye Daylights '200' something..

You must have the older model Daylights. I've got the same one.
Got mine & spare bulb at Cecil Walker Cycles. :confused

From the site John posted you'll need a Part No = GH15 (Push-in, 6V
1A, 6W)

Greetings,
Go get a decent halogen bulb for your local bush camping/outdoors
shop, if it is a decent one, they will have them. Not cheap though. Well
worth having for the better light output, as you know.
Regards,
Ray.

A tip for you dutch, if two bulbs of the same "technology" has differen
wattages, the one with the higher wattage will "burn" brighter, but als
consume more juice from your battery. If no wattage, then multiply th
voltage with the ampage, and you have the power

if this is for the black wonderbike, you should get some blac
halogens.

yee gods no! I use the built-like-tank-when-in-commuting-mode-mtb fo
such adventures.

My 'Company car' (refer other threads. basically got me boss at th
time to buy me the bike, lights and assoc. gear...) so to speak.
wonde in the winte rmonths when all thawts of speed go south and al
thoughts of safety loom large on front of th
not-so-flyin-Nederlander.

then again, black halogens.... nah. no fun dodging fool

Thanks for mozzing me FD! Got on the bike to ride home last night
switched on my light, got a short flash, then nothing. I'd blown MY 6
6W globe! I use a 4 LED flasher on my helmet and I put the emergency
light on the bars, so I wasn't without light

I did have a spare pair of globes at home, bought from CW before th
last Kona. Price was $25 for 2

Long time ago, they were a common (and cheaper) Eveready globe
available from McEwens or Dick Smiths, but haven't seen them ther
since

I run them with 7.2V Lithium Ion batteries so the overvolting gives
much brighter light but a shorter life span. I've got some 6V 10
globes as well, but they melt the dynamo light fitting that I use, i
run at > 6V

Perhaps for commuting I should run them again at 6V - the globes laste
for years. Or get another LED flasher for the handlebars. Save the L
batteries for off-roading

Running a light globe at 10% over-voltage will increase the light output by
25%, and shorten the life of said globe by 50% or more.

We ran an 8V 50W projector globe in a main-frame printer for over 4000 hrs
at 4 volts and it still worked. At 8 volts the globe was rated for a life of
16 hours.

Ok, did some more research (ie, Google) & Slaw's post got me thinkin'

You could try a globe for a Dolphin torch. They're a 4.8v 0.75A, i
3.6W but if you overvolt it at 6v should be bright enough. Note tha
overvolting shortens bulb life, buuuttt they are a cheaper globe tha
the Cayeye replacement, ie $2.35 at DickSmith, Tandy or same for pac
of 2 at Jaycar.

Give it a go, you can only be left in the dark if the globe blows
(carry a spare) :
