Anyone tried the Coralvue Reeflux 10k bulbs?

[PUGroyale]

alright who's the guinea pig

I'll be the guinea pig :lol:

This looks like just the bulb I've been looking for. Sanjay puts the PPFD at 86.1 and the CCT on IC ballasts at 15953. This means it has the highest PAR of any of the SE 14K bulbs [even the AC] yet has a better CCT [for my tastes anyway] of 16K. Sounds like they're worth a shot to me.

Should be here mid week and I'll be able to post some side by side comparisons with my Hamilton 14K's [albeit year old Hamiltons]

PU - You talk like this is a 14k, I thought it was a true 10k?

not sure what you mean It is supposed to be a true 10k the only true 10k if you listen to CV's marketing. My taste in bulb color though runs in the 14k- 20k range... I like the blue, it's just my preference. So what is the common lament of folks who like the color of 14k or 20k bulbs??? I wish they were more powerful! That's why I'm gonna try these. PAR in the lower echelon of the 10k bulbs with a correlating color temperature of 16k. just may be the best of both worlds ? We'll see...

Dave:

The ReefLux is definitely a lot less yellow than most 10Ks, and has a more white/blue tint. I'm not sure it looks as blue as a 14K bulb, but I haven't seen a side-by-side comparison, so I'm looking forward to seeing your pics.

Cheers,

I've been using the Hamiltons for 2 years, and just switched to Reeflux a couple days ago. I want to reserve final judgment until proper burn-in, but the Reeflux definitely seems brighter and a touch more bluish. Will post tank comparison pics later.

What ballast you running Rich? According to Sanjay, this bulb has a CCT that ranges from 11000k all the way up to 17000k depending on which ballast you use.

exactly what i was going to write...i think it's odd that it ranges so much, but still, i like the par and the color...

It's a standard magnetic ballast, but I'm not sure of the exact model.
I purchased it from Marine Depot with a Hamilton pendant:

It's a standard magnetic ballast

I couldn't find the numbers for 175w bulbs/ballasts, but the CCT for the 250w bulb on a standard magnetic ballast is the highest @ 17000k.

Sanjay mentions that bulb temperature classifications [6500 k, 10k, 13k, 14k, 20k] are basically a way to group bulbs and/or a target temperature goal for the manufacturer. As I understand it, The actual color temp [or CCT] will vary depending on ballast/bulb combination and may be significantly different then the bulbs classification. That's why I'm trying them. If they're anywhere near the look of a 14k but with higher PAR... I'll be happy :smokin:
...We'll see

What was the CCT on a IC e-ballast?

 

[PUGroyale]

What was the CCT on a IC e-ballast?

15953k

 

[rmendis]

Thanks for the info, Dave.
I suspect that my 175W mag ballast probably runs the bulb around 11K. But that's just a complete swag.
Anyone have a PAR meter I could borrow? =)

 

[PUGroyale]

Thanks for the info, Dave.

No problem I'm just trying to make sense of it all myself :lol: BTW... the color temp is measure by spectrum analysis I believe. PAR would be the bulbs power. ... I think

How will a 250 watt DE 10K bulb look under HQI ballasts? I'm debating between the 10K and the 14K. I'm just worried that the 14K won't be as bright as I'd like, but I definately don't want any yellow from the 10K.
I'm not 100% happy with my Phoenix 14K's. I like the color but they appear a bit dull.

 

[PUGroyale]

I hope you're not asking me :lol: This is just my interpretation of the data and may include some wishful thinking on my part Sanjay doesn't have data on the DE bulbs on his site yet. The CCT for the SE bulb on HQI is 10093k. You can check out the spectrum plot, the HQI ballast seems to cause larger spikes in the white and yellow range than the other ballasts.

You might also make sure you're looking at the correct bulbs. The CVreeflux vs. standard Coralvue's. hth

You're correct. I had a brain-fart there.

 

[NoSchwag]

Cmon' I know someone has some in-tank pics.. I'll take with or without actinic at this point..

 

[rmendis]

Ok, here you go.

Left: Hamilton 175W 10K SE on mag ballast
Right: ReefLux 175W 10K SE on mag ballast

Note: Hamilton is 1yr old, ReefLux is 4 days old

Looks good! I just ordered 2 250's for my tank. They will be here tomorrow. I have been running ushio's for the last year will great results. I hope the reeflux's are as bright with more blue compared to the ushios.

 

[PUGroyale]

Ok, here you go.

Thanks Bro! That really makes the year old Hammy look sad :lol:
I sure hope the 250w is as nice. ETA on mine is 8/20

 

[NoSchwag]

Perfect color.. Look at the blue shroom.
