Can I ask where you got the Dinotte? Was it a one off that someone was selling or can it be found somewhere for that price?古強者死神 said:Hmm I just got the Dinotte Ultra 5 for 150$
this would make a great helmet light with a small DIY on the power circuit, but that would bring it closer and closer to the Ultra 5's price tag.
I don't see any mention on the Danolite website claiming that this light features any additional circuitry. :skep:anavig8or said:An x-ray revealed NO efficient circuits or any power converter whatsoever. Disappointing especially since the website makes this claim.
It has been proved on many occasions that halogen lights in fact appear brighter then LED based lights on digital cameras, as they emit more light in the infra-red spectrum, which the camera picks up and represents as light. Using a digital camera in an "automatic" setting is foolish (read useless) for making comparisons between lights anyway.anavig8or said:The automatic cameras will make the Danolite look as bright as an aircraft landing light.
While not ideal, it is quite possible to use single 3 watt Luxeon with a BIN that shows a reasonable forward voltage and direct drive it off 4 AA NiMh cells. As you mention, alkaline cells would not be a good idea, however with a carefully considered resistor choice for the BIN Luxeon being used, it is still quite doable without a regulator.anavig8or said:My last ding on the Danolite is that it can't operate with standard AA batteries since it has no power converter. Put 6V on it (instead of a rechargeable 4.8) and look quickly because the LED WILL burn out...so be careful.
Again, I don't see how Dan is making "deceptive claims"?anavig8or said:OK, so I'm down on this light because of the deceptive claims.
From my point of view the Danolite looks to be very much "finished". If you insist on blowing a fortune on "throw away" alkaline cells and have a sound knowledge of electronics and know for sure what you're working on, it would be very easy to make a simple constant current regulator for a just a couple of dollars.anavig8or said:It really isn't a finished product, like the DiNotte. For about $15 more in finishing, the Danolite would be THE LIGHT. Right now, it is a $30 or $40 accessory!
I understand that performancebike.com had the DiNotte going cheap recently. Not sure if that is still the case or not.CDtofer said:Can I ask where you got the DiNotte? Was it a one off that someone was selling or can it be found somewhere for that price?
No not exactly. I think I stated that a single 3 watt LED might not quite compare in brightness to a 10 watt halogen. I also stated that the higher colour temperature of LED's gives the perception of a brighter light. With the right optic or reflector choice you could illuminate an area just as well as a 10 watt halogen.So we're down to one deceptive claim. Low_Rider has confirmed my observations with respect to the comparison between this LED (and any other LED that is being used in bicycle lighting) and a 10W halogen lamp.
