430nm LED

[jancorwin12]

I'm currently planning to customize my led setup and came across the use of 430nm. violet po ba ito (hyper violet) at effective po ba yung wavelength na ganito?

maraming salamat po sa mga magbibigay input!

428nm is one of chlorophyll A and some pigments' absorption maxima. Pinakamalapit na yang 430nm and it will be good for both growth and coloration. Maraming flourescent proteins rin ang lilitaw diyan na hindi nakikita sa ibang nm.

BTW, check out the evil cluster build in nano-reef. Ang gamit lang nila typically ay isang 4000k neutral white bridgelux, 2 cyan, 2 blue, 2 royal blue and the rest puro 430nm violets. Hands down the best combination for growth and color rendition. Puti pa rin sa paningin pero litaw lahat ng kulay. Panalo pa sa PAR lalo kung naka ledil optics.

This is taken from different sites - advanced aquarist and nano-reefs to name a few

Eto ang magandang gawing reference kung gagawa ng broad spectrum lighting:



Andiyan na rin pati yung chart para sa photocompensation, photosaturation and photoinhibition points ng ibang typical corals.

maraming salamat po sa napaka-informative na sagot. Mas mahal kasi yung 430nm compared sa common wavelengths, now I know na may equivalent value naman pala presyo niya. salamat ulit!

NP sulit na sulit yung presyo niyan, di mo na rin kailangan ng green or red supplement kung marami ka niyan. Ingat lang kahit dim tignan yan malakas ang output (usable radiation) niyan.

pahabol po na tanong, meron po UV leds na hamak mahal sa ibang leds (triple the price). I browsing the net on the benefits but all I can find is for additional colorationg brought by corals trying to protect themselves from the UV light. Any inputs on this?

[jancorwin12]

ano ibig sabihin ng usable radiation? dangerous to human health?

[seth]

nope. safe yan. No need for LEDs below 400nm.

PAR - photosynthetically active radiation
PUR - photosynthetically usable radiation

thanks ulit!
