What emitter is this using?
It says voltage 13.1 V and current 1.4A but then describes it as a 10W led?
Looks like Osram Ostar. This is the same head that MB Sub (I think) sells as an upgrade to HID units... If it's putting out 1000 lumens it's probably the Osram Ostar 6-die 27W LED. I don't think there is anyone making 1000 lumens with 10W.
P7 would be more like 3.6V and 2.8mA and MC-E could also be 7V and 1.4mA or 14V and .7ma.
I don't see what would be in the range of 13v and 1.4mA?
where do you have seen such a construction on our site???? :thinking:
Looks like the aton test tube to me to, or either a copy.
The aton uses 1.5amps current draw and the ostar... These details i got from Marcel who designed the aton test tube, still have the email.
So they over drive the ostar which might give the 1000 lumens advertised.. I dont think they use the 27w ostar more likely to be the 16w..
I have seen this light at BOOT and it uses a Ostar led.
I cant remember which ostar it was the 4 die or 6 die:shrug:
I'm sure you are correct so it would appear that the specifications of the light are incorrect. I don't know of an Ostar that gives 1000 lumens at 10 watts.
edit : I have emailed the company and asked the question
Here's the email i sent to marcel back in december and his replies are in bold.. hope this answers your questions.. apart from which ostar is used..
I came across your new aton light heads http://www.direxplorers.com/specialist-dir-kit/7630-new-dimension-dive-light-diving-innovations-repairs.html and to be honest I’m very interested but I would like to know more as there is limited information at present.
1. How many Lumens does the aton1 and aton2 produce? >>> ATON I does approx. 1200 lumen / 22.000 l/m- ATON II is brighter-details will be public on BOOT show
2. Which LED are you using? ATON I uses the Ostar.
3. How much current and voltage does the test tube LED need? So I can workout battery runtimes form the selection of packs that I have spare. >>>Current draw is 1,5A.
4. Is there any controlling electronics? If so what benefits does it provide?>>> Yes of course. The electronic dropps down the amp supply to the led when your battery is empty. So the light is not switching off, like HID. The diver can indicate the end of burntime if the light gets less bright. It starts flickering before the battery can get hurt.
a. Is there only one power level?>>> Yes, horgathian like.
b. Does it shutoff when the battery pack is low to avoid damaging the batteries?>>> Answered previously
c. When it reaches low voltage does the led step down to a lower level to give more light instead of shutting off completely?
d. Thermal cutoff if the led gets to hot?>>> Not necessary.The construction allows even on land overheat.
