![]() Heres everything and anything you wanted to know about xenon,here youll find a graph comparing xenon to other lights including the sacred "cree" l.e.d
they explain how xenon is a micro mh that uses different gases for firing. Check the graph and the paragraph next to it good food for thoughtwww.xevision.com/hid_products.html |

![]() Just a note, Cree claims efficiencies of around 100 lumens per watt also, depending on chip temperature. http://www.cree.com/products/xlamp7090_xre.asp This is only one of Cree's LED chip products, and there are many other great white LEDs by companies such as Osram (Sylvania) and Lumileds (Phillips).
I'd be curious to see the PAR value of Cree's cool white LED products. I like LEDs for the fact that they are solid state ie: less prone to breakage, and they are rated to last 50 000 hours, though the actual useful life will be less for our purposes. A big detractor from xenon bulbs is the rated 3000 hour life, which is less than both MH and fluorescent... wow, hope the bulbs are cheap! I'm glad that forums like this exist so that open discussion can make us think of new ideas. If xenon can produce higher PAR values, perhaps we will see the advent of 150w xenon metal halides in the future... though I doubt that the aquarium / horticulture segment of the total metal halide lighting market around the world would be enough for manufacturers to start producing larger xenon bulbs. If indeed the lumen output of these bulbs is lower than our traditional metal halides, I can't see these lights making it as a replacement as they are not fit for the traditional use of HID lighting (task and area lighting) even if the light is superior in terms of plant growth. I still maintain that this (xenon) is probably the BEST way to light a pico to small nano (less than 10g), at least if you want SPS or other intense light requiring organisms and don't mind changing a bulb more often than usual. I suppose you could use PC, but then you don't get those glitter lines that I so love with MH lit tanks.

![]() 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
![]() 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"
![]() Perhaps but it's easier not to be skeptical when bulbs are produced for the sole purpose of use in the aquarium hobby. |
