I could give you numerous links to waterproof led strips in the 460-470nm range if you're only looking for 'on/off'

dimmable, yes. It's the one feature I'll miss with T5s

Yes, Steve and I used to battle over this all the time

In a weak moment of not being able to order Radiums, a couple used Mitras came up on the market.

You can buy dimmable T5 ballasts ... 1-10v

I can't help you with the day/dusk LEDs if you want them dimmable

OK, I'm dyin' here to post them for someone, so, here's some LED strips you can add to your fixture for blues/actinics
All are close to or between 460nm to 470nm and are waterproof strips that you cut to length and add your own power supply

I have a question: For those that are considering doing a T5/LED combo light, what combo do you think is the right combo? Since most LED fixtures are primarily Royal Blues and Whites, what's the ideal T5 additions in your opinions?

With my ATi hybrid, I added 3 blue plus, and 1 coral plus bulb. Blue LEDs are very blue but the spectrum they emit are very narrow so a florescent blue bulb would cover more spectrum's that may or may not be important for coral coloration.

My take on LEDs is why are companies keep upgrading their white LEDs and keep developing them. Most tanks out there cant run their whites 100% without burning corals, I would like them to concentrate development more on blue/royal blue/ any beneficial colours. I run all my blues 100%, even back in the SOL days with 40 degree optics they did not burn anything, but then ramp up 2% whites I start to see paleness.

With MJCs frag tanks, all lit with LED + T5, we find the tank with CREE brand LEDs + T5 get more intense coloration than our Bridgelux brand LEDs + T5s. The difference is subtle to dramatic depending on the coral, also the colouration of CREEs are nicer than their Bridgelux counterpart IMO.
