we need your help for the perfect light

Damn, i lost.

I'll bet my wife on metalsub.
Hope i'll loose again; Can't wait to send my wife to you

colinicky

ROFLMAO I'll stick with the 20 bucks thanks


ps your still wrong
& I was told it by the manufacturer concerned

I managed a reasonably small beam, but as you say it was still much bigger than normal. Then again, I'm hoping for floodlighting not spot from this. They are rated 700-800 lumen so that's fairly normal for LED isn't it?

Anyhow, they're cheap so that's one tick in the box for me.

When I last looked the Ostar wasn't freely available. The reviews did look fantastic though! Can I ask where you get them from please? I'd like one to play with!

Has anybody looked at the Titan Hydro-lights? What are they like?

fletcher

AARRGGHH, Colin, i can't sleep anymore because of you.

No, seriously. If that manufacturer bring on the market such a light, he will sell many.
The salvo design is great but the led is a 6° focused. I like focusable lights so it's a big point for your manufacturer.
The new ostar led is equal to a 18 watt hid. So if that light can explode a 21 watt hid, it will be a small revolution.
Now the most important will be the price.I don't want to sell my house to buy that light.

So wait and see. Am very impatient.(but you already noticed that)

I dont like products without technical information. There is nothing of information.

I would like in my perfect light:

1, output of around the same as the HID200 metalsub or brighter
2, LED bulbs - durability and low battery drain
3, build quality similar to solus - indestructable
4, small head like solus, umbilical design
5, power on/off on head - proximity switch like solus
6, long burn time 3-4 hours minimum
7, interchangeable battery packs like metalsub.
8, long, thin design of battery pack, like metalsub - allows for easy mounting on unit, unlike solus - the bigger battery is about the same diameter as a 5L cylinder!!!
9, no memory effect - Li - ion battery cells.
10, depth rated to 200m or more like solus.

basically, the best features from metalsub and solus combined

Agreed, the emitter area of that LED is huge (in the LED world)
It would be difficult (not quite impossible - but close enough) to design an efficient refractive optic to deal with that LED.
A reflector would work but the beam would be horrendous and the efficiency would really drop.

Generally a properly designed lens system would be much more efficient than a properly designed reflector.

Agreed. At the rated output (which is only ever likely to be achieved in a lab with the LED stuck to a chiller plate) this LED produces a whopping 34 lumens per watt. The LED industry passed that milestone about 4 years ago.

This is only right, because it exist still today nothing in good reflectors for LED.
But this is only a question of time

True, but Ostar aside, the only other solution is a bank of better performing LEDs. More expense, more engineering.

I am looking at drop-in replacement rather than new item, so having a small LED cluster is important. 800 lumen is still ~=65w halogen I think? So appropriate when looking to replace the small 20w halogen used in for example my DiveRite umbilical with its pathetic 2.5Ah SLA battery. That's a quick gain in brightness for limited outlay.

For the normal sized halogen, maybe a drop-in Ostar module, or small cluster of crees might be best. Most cannisters I've seen have got room for well-designed drivers to sit between battery and lighthead. There are lots of old halogen umbilicals out there which could be given a new lease of life quite simply and quite cheaply. Maybe a kit?

I know this is a bit of a thread hijack and you're looking to make something new and shiny, but don't forget there is a large market out there of divers who won't spend £500+ on a dive torch but would spend quite a bit to upgrade what they already have.
