I've got an oldish set of Hope HID lights, 3 years old, anyone know how many lumens they were, just want to compare to the latest lights that are all rated in Lumens.

About 500

Er, and the rest. Most HID rate at about 800. Your eyes don't register light in a linear way though, so more lumen may not means you see more, the very white light that HID produce also makes them seem brighter.

Yes about 500 when new but this will drop off as the lamp ages, Hope rated them at 450.

I had the 2nd version. (Not the submarine type lamp using). It rated 600 lumen.

cheers. SO pretty competative compared to current LEDs.

Hope instruction book rates the HID @480 lumen.

not price wise (if you can live with a cheap HK import), or longevity wise (as HID lamps wear out, LED's supposely don't).
All of my m8's are replacing their Hope HID's (which were fantastic at the time) as they wear out with DX P7's

If anyone wants to sell Hope HIDs, I'm looking for one to experiment with to upgrade to over 1000 lumens.

This isn't true. Lumen is not a physical a measurement unit. It's adjusted for human visual sensitivity.

@nickc
The only HID capable of 800/900 is the NiteRider Slickrock.

Every other bulb before this has been about 500 max. The NR bulb (can't remember the vendors name now) was the first one to be able to do 900 so there is no way the Hope could have been that high.

This is borne out through testing also.

mmm, Interesting, I've got a P7 torch aswell. Side by side I'd say there the same.

So how many hours are the Hope HID lamps good for and where are the replacements ?

The Hope HID will burn for a little under 3 hours. There is no warning when they expire though, they just go out. 8O. I found it best to swap batteries roughly 2 3/4 hours,(2 batteries is very important)and you need to keep a keen eye on the time.
I have been reliably told the bulbs are £70, although Clarymorris sent hers back and Hope replaced it free. 😛

Sorry, I meant how many hours before you need to replace the bulbs and where can you get replacements.

I can supply cheap replacement bulbs (life of the lamp depends on how many times you turn them on & off)

Hi Snaps, I'm intrested, what the price ? Cheers.

The last ones worked out @ £53 each

Yes TS bought one from me – £53+post
