Phoenix 14K bulb ?

[Mchava]

here is something I find kind of wierd, on sanjays site it shows that the phoenix 14k and the blv 10k are the same par 88. But when I just measured them I got higher par readings from the blv then the phoenix. Kind of wierd since they are both suppose the be the same. I also noticed that the 10k are alot brighter then the 14k. Simce like I might be going back to 10k here soon.

10k is almost always going to be more PAR than a 14k...that should be no big surprise, though if Sanjay's test says they are the same, I would bet they are probably pretty close. Perhaps the whiter color of the 10k just looks brighter...I dont know what to tell ya there. Numbers dont typically lie

Did you measure with or without a reflector? what devise did you measure with? How far away from the bulb did you measure from? Did you measure under-water or not? What where your readings?

There are a ton of variables that can effect a reading, especially when they are not done under the same circumstances, there is also variation between bulbs (even when the bulbs are the same). If you can answer the above questions then it will help in answering why you got different readings.

I’m looking to increase my lighting. Not knowing too much about lighting, could you tell me if the special offered by Premium Aquatics would be a good choice?

I already have 2 of the same housings with 250W Phoenix 14k DE lamps but they are running on Ice Cap electronic bulbs. What difference would the PFO Electronic Ballast provide? Thanks

This setup might save you some money.
