Well first realistically you won't get 13.5 or 10 years out of your LEDs as we already agreed. The same unrealistic numbers are given to both halides and T5s and previously discussed. Second how does...

I would say that PAR is obviously related to CCT, different bulbs produce different PAR based on this, but not so much for the change of PAR overtime from bulb wear. A decrease in PAR would be more a...

Bulbs with a lower K rating typically produce higher PAR because, as you said, it's related to the amount of useful radiation (more of it in lower spectrum bulbs). So if PAR and spectrum wear where...

I'd agree that six years would be a reasonable estimate at this time. That being said with the current design of LED fixtures the energy savings will likely never give a payback if you have to...

Kind of my point guys. LEDs are rated for 10 years before a 30% drop in intensity occurs just like halides are rated for 5 years. So yeah halides only last a year before par is too low so how long...

You can get a Red Dragon Pump in that range and it can be used internal or external. You won't find a quieter pump but unfortunately you probably won't find a pricier one either.

I'm pretty sure I can get that done here for you if need be. I had a couple pieces done a few months ago that I recall being around the same size. If you want me to look into it just shoot me a PM.

The back of the mirror will contain tin chloride, silver, copper, paint and other chemicals. So not too good for saltwater.

I was under the impression the HQI or DE bulbs don't have the UV filtering outer glass and require tempered "low emissivity" glass. It's the Mogul or SE bulbs which have the UV filtering outer glass...

Glue an extra fitting to some extra pipe using the same ABS glue you used on the tank. Let it sit overnight and see if you can pull it apart.

Typically it's not a high margin product and if one were to try and make some money on it people would just go elsewhere which is the last thing a retailer wants.

Any glass shop should be able to get 3mm tempered glass cut to the size you need, phone around and find the best deal. Some will apply a minimum charge so it could vary.
