Just asked for a link, I never said you're lying but you haven't showed us anything yet except a description of HID lighting. How about a link to those par values you found??

I cant find the par value site yet :( the last link was just to show that a xenon is infact a mh using same burn temp and metal salts,also that last site was mentioning how a xenon produces light more efficientlly than an led by 3% I think it was. That was to put to bed the notion that xenon is less efficient than a traditional mh. I'm sorry I'm in the middle of a move and dont have much more time for research but im sure if you look you can find the par value site....or you could just take my word for it lol The results were this watt for watt the xenon hid has a slightly higher par value than a traditional mh.

My personal thoughts remain that with a little tweaking this technology is perfect for a nano reef 14gal and under where a 70w halide isnt practical. Xenon hid will never replace mh 70w+ because its the same technology just different firing gases that arent needed in a bigger bulb.

I enjoy debates like this,I hope no one takes me negatively just bothers me when people dismiss something without either trying or researching it first.

The fella here powering his 5.5 is happy with the light he claims no heat issues and looking at the pic his tank is glowing something fierce,his corals look happy and have good p.e. As for the comment that your corals have p.e even in the dark...well duh but try keeping them in the dark for a week
or two (the time he's been running this light) and see what happens lol

I'm sure there were skeptics when MH and T5's were first considered for aquarium use as well.

Heres a thought for a reflector being as its a headlight........car salvage yard lol If your thinking maybe voltage is a concern being at the moment they are just car parts,check out the wiring on these l.e.d pico setups people ar loving;buck pucks and tigers and bears oh my lol

Well keep looking cause that's what we or at least what I would be most interested in seeing. I already knew Xenon lights used the same technology as MH. You should be able to find the site in your browser history. It seems a little strange to me that you found the very thing that makes or breaks the use of this lighting and now "you can't find it" :confused:

Perhaps but it's easier not to be skeptical when bulbs are produced for the sole purpose of use in the aquarium hobby.

Arent you friendlly.I've spent a week researching this....think about it b efore you go accusing me of being a liar AGAIN Par value is the percentage of light that reaches the target after disspation via heat and such is it not? Now take a mh bulb and compare how far the light goes to a headlight on a car better yet look directlly into each because your begining to annoy me :)
Through my research I've found what I wanted to know and believe I've provide enough proof that this is a viable technology,if thats not good enough for you thats not my problem try google,then come apologise when your done

Dont forget im talking watt for watt 2x 35w xenon vs 1x70w halide I would only use 1 but I dont think you get 10000k less than 70w with halide.

Anyway im done for today good luck with your search,arent you staff im sure you have acess to a par lux candlewatt thing a ma jobby

Here's a link on nano-reef. The setup looks good on the tank. There is lots of debate on powersupplies etc.

IIRC they do put out 4000 + lm, but I'm not going to do the research again.

Now you guys have me wanting to get mine running again. Maybe I'll look into that tonight. More SPS in the tank now and it could use more light. I do like the looks of the xenon.

Yeah I admit I'm the rude one for asking for a simple link to help clarify your blunt statements. PAR, as already stated, is the Photosynthetically Active Radiation which is pretty self explanatory and the beam created by a headlight is a result from the reflector not the bulb.
Just because something makes sense in your head doesn't make it fact and just stating you've done research doesn't give credibility, the most important part of any research project are the references.

Hey hillbilly a guy who's ACTUALLY tried lol,I found a site that claims the 55w version runs the ballast way too hot and 35w is the only way to go,could this be the source of your ballast issues maybe?

Sphelps,thanks for the reminder I wasnt too sure about that,sorry i'm not able to produce links to every site I've visited in the past week,I didnt realise there would be a quiz.....I can see theres no getting through to you so I give up just cant get over you implying im a liar,I dont think I've done anything to warrant that behavior,anyway have a nice life:)

Everyone else I hope you learned something,thanks for tuning into my thread
