No - you have to unscrew the unit and then carefully reassemble.

Nope, IMHO replaceable but not designed to be easily changeable.

YOU CAN PURCHASE THE INTERNAL BATTERIES
once batteries are replaced they would need charging
no need to carry a spare battery life is good once fully charged

Yes you could change the battery whilst on the road. Two allen screws in the front release all the innards including battery pack. Battery can then be unplugged and replaced.
Charging your spare battery pack would be the hard bit!

I found this difficult-I took my first version of this light apart having dropped it (hence replacement now) and found it fiddly to get back together properly with no indication as to which type of battery was in use. I am sure this information is available butI don't think that this is a convenient solution for you. I did get 6 hours out of mine on near full power though when new though

The charger works at 240v, 50Hz and I can't see why it wouldn't work in Oz with a suitable plug adapter.

yes, you need an adapter to plug the charger into the wall, but the charger unit itself will charge with 240V

Purchased in the UK, charger states 100-240V 50/60Hz.
Localisation lead supplied uses a C7 connector.

If used in Austrailia then the charger would work definately
it will automatically switch over
it runs from 100v - 240v
look at the specification guide or the charger itself

Yes, just get a UK plug adapter - works great!

I use this light and the Garmin 705 daily. As yet I have not experience interference.

I have a wired bike computer
obviously no interference
I was recommended to buy a wired computer as wireless can cause trouble and other things around u can cause interference even if monentarily
no hassle to have a wired computer

i have a polar that sits right beside my light and doesnt suffer

Can't tell you about the Garmin, but I have been using the Cateye V3 with no interference for 6 months, the digital signal ensures that the discharge from the light doesn't block the signal

You will be fine with the Garmin and this light. I have both and they work well. My problem is the strength of the clamp of the light.

Do not even try it will end up in tears, heavy, poor anchor.

My husband rides 13 miles each way to work. Every other week he is on afters and doesn't leave work until 10.30 pm. His journey is through country roads with no lighting and he thinks this product is brilliant. He can see the road and in front of him with ease and is one less thing to worry about when riding home in the dark. Would recommend it for night or low light riding

This will be fantastic for Winter use or Off Road
even on lit roads on FLASH MODE
you will be seen

I have used it off road and have found it to be a massive improvement over what I had previously. To me it perfoms very well and particularly in wooded areas (Sutton Park in West Midlands) it lights the path up very well. I have not experienced any more expensive models but would imagine that it would cost quite a lot more to get something slightly better. The rechargeable basis of this units make it ideal since every time I go out with it, it is fully charged.

Buy a hope light, expensive but you wont regret it.

I bought one 4 weeks ago and the bracket has already failed so I would not think so!

I dont know if its been upgraded (there is another you can buy and use instead) but honestly unless youre taking any big hits or going off road you'll be fine with the included bracket. its definittely stong enough for the weight of the light.

Buy the updated bracket - no problems then.

I think the bracket has been upgraded.

The one I purchased came with a update manual about the bracket specifically.

Balancing the unit I have on a pen, indicates the weight to be centred at the bracket.
The full model number printed on the underneath of my light is HL-EL610RC.

No, the charger lead plugs straight into a socket in the body of the light.

Battery charged in-situ.
There is a charging socket on the bottom. Protected with a rubber plug when not in use.

no just plug the charger into the mains
then plug the other end into light
once charged the green light will show

No, the charger connects via an external connector protected by a rubber plug.

Irrespective of the candlepower/lumen comparison I can tell you this light is fine for winter commutes on unlit roads.

Depends how it's measured so difficult to compare.
Result can also be subjective.
All I can say is with this light I've finally found an LED light with sufficient beam shape and depth for my winter commute on unlit roads. - that doesn't cost more than my bike!

this light is extremely bright
for distance wide beam and a good real white light
15,000 candle power is really really bright more than what you will require for your winter commutes especially if you use on flash mode on dark or lit roads will light up reflective signs upto 10meters away
three settings constant high beam & low beam and flashing mode
for the money you will not find a better light under £100

15000 candles is bright, very bright! Put it this way, I go cycling at night with my mates on unlit roads and its bright enough for all 3 of us to see the road ahead while going downhill at 30 MHP.

Purchased in the UK, the charger is a universal type: input 100-240V 50/60Hz. Plug in localisation lead uses a C7 connector.

the charger will work in US
runs from 100v - 240v will change voltage as soon as you plug in to mains
all u need is a plug adaptor converting UK to US these can bee purchased in most places or in an airport
Walmart or similar place

The light came to me (Australia) with a UK plug.
I just unpluged the lead and replaced it with a stardard figure 8 type (two parallel in sockets) with Australia plug for $10. They are standard on shavers, lap top chargers etc
The charger wil take 100 to 240V and 50 to 60 Hz, so it will work fine in the US

Comes with bracket H34.

comes with a handle bar mounting bracket
buy a spacebar / grip re locate other lights thats what I did
work perfectly

Cateye H34 Flex Tight Light Bracket - available separately. I have one on each of my two bikes (road bike for early morning training, and also my commuter bike)

Enclosed instruction sheet for HL-EL610RC lists "NiMH 4.8v 2500mAH" #534-1865N as replacement battery.

You can purchase more internal batteries if you needed to
easy to replace instructions are supplied when you purchase this light

You shouldn't need one; the battery is integrated, the unit comes with a charger and mine's been going strong for ~1.5 years and counting!
