Been looking on amazon for replacement 3w diodes for my fixture and I found some that are either 445-450nm or 455-460nm. Any ideas of which I would be using to replace my 450nm diodes which have burned out? They both look blue to me, which is the one that corals grow on? A ten pack is only 6 bucks.

Can anyone point me in the right direction?

Try 445 to 450 nm.
the more you go up........you end up Cyan ( Blue to Green = 505 nm)

thanks, also picking up some 120 lenses (for red and green leds) to balance out the colors. This repair of my ocean revive t247 fixtures is going to get another 3 years of life out of them.

Lenses , is anther headache , do NOT go what they advertise , 120,90 etc. most have huge destitution , most wont reflex what you inspect, most look same, i order 7 dif. until i got some what i need. Buy few , test it, project the light on one temple , compere , all look the same , but very few do the job.

Ah thanks, I did ordered the diodes and lenses. The 120 was to just spread out the odd green and red diodes to prevent the spot light effect which I get from the 90. Doesn't have to be perfect for wider angles.
