That's frustrating.
Beautiful tank! Way above my pay to maintain and light with Leds
No kidding. We are all not so fortunate as to 8-10k in lighting equipment likely gifted to us. I’m curious as to how many units they sold based on his and paletta’s endorsements alone?
I agree w/ you but the point wasn't cost (well mostly not).. just the magic photons...(couldn't resist)
I deleted the speculation part ..
NOW before you go all dogma on me I'll freely admit there ARE differences between light sources.. Physics dictates it.. What they mean is still a relevant question and NOT answered fully...
Believe what you want.. and use what you want.....I don't care..
Hard Core "Collectors" of any kind are sort of a breed on their own and, frankly, have little to do w/ "little people"
for fun.. 10's of $1000's of dollars of Metal Halides..

Sorry.. Just saw the date................
Interesting...Yeah it is outdated. I live 15 minutes from Todd(owner) and he does have a pile of stuff for sale, but it’s not as big as that. It needs updated. A few years back I think I bought his last 2 lumenarc large reflectors. But none the less, he switched to DIY leds, then the next year to orpheks and now he last few years to radions.

My hang up with the led industry is the misinformation on cost of operation and upkeep.

Osram/Radium 20,000 K Lamps
Apparently depends on lamp..Figure 3 shows the spectral distribution of the various 20,000 K Osram/Radium lamps tested, and Table V presents the PPFD. Table VI presents the drop in PPFD output when compared to new lamps. Here again, one of the lamps at 6500 hours of life seems to be an outlier (an anomaly). As seen from the data, these lamps tend to lose their output at a much higher rate compared to the 6500 and 10,000 K lamps. Year-old lamps had lost about 40 to 50 percent of their intensity. Unlike most of the other lamps, these lamps show an almost uniform reduction in intensity across the range.
THAT is an issue for old "PAR" meters like the Apogee series and Seneye..Clearly as indicated by the data, there are larger (faster) drops in the intensity in the violet and blue end of the spectrum for all the lamps. Hence, lamps with higher CCT tend to have a higher rate of intensity drop.
For those "complaining" about LED marketing FUD.. How much did that cost?The changing of MH lamps every year was the biggest waste of lamps ever known.
I liked the post - but I'm sorry I don't quit understand it. Thats probably because you didnt quote the initial post you were responding to? I cant tell if your pro MH Pro LED or pro neither - just making a couple points - and I"m interested in the pointsyou don't dim MH's.....s00...
anyways it was to point out that expense is relative...

Well there is that but I'm just trying to make a teeny point.. Not common in MH's VERY common in LEDActually if you get reefbrite ballasts they’re dimmable
The changing of MH lamps every year was the biggest waste of lamps ever known. In the 10+ years of using Reeflux / Radium / Phoenix 250 w SE lamps the average was 16 to 18 months with only a 10% drop in par when I changed my lamps. I had one lamp go 24 months with only one dropping 10% at 12 months. I had several reefers over to my home and I bet them which lamp was 1 month old and which was 24 months and they couldn't figure it out because there was no color change and human eyes can't tell 10% change in Par or foot candles.
And it would take 2 x 100 watt black boxes to equal a 250 watt SE Reeflux / Radium / Phoenix lamp installed in a Lumenbright pendant. I tried /tested the 100 watt Mars Aqua leds. I loved the color but at 50% I only achieved a Par reading of 200 in the center, after one year I had to crank it up to 100% to keep the 200 Par reading in the middle. With my MH I was achieving 200 on the sand in a 27" deep tank. The following Mars where on my 180 24" deep tank mounted 12" above the tank to get even lighting. One the left and center where at 50%, the one on the right which I had for a year was at 100%
Point is cost is relative..But beyond that I completely disagree with your cost comparison analysis.
Eye is easily fooled.. and we, as humans, adapt.I too noticed I could use a MH for up to two years. At that point it's just guilt. lol
Unfortunately I didn't have a par meter then. I couldn't notice a difference it was so gradual.
Point is cost is relative..
I freely admit MH's are probably the most "cost effective" entry point in this "hobby" and work just fine..
But that is for others to decide how much they want to invest..
That's universal across any hobby..
you think people w/ simple MH's do not year for a Geisseman??? Of course they do. Some... Call it a bar to reach..
Nothing in this thead points says "guide to beginning Reefing"....where your main argument seems to be..
Just as black box people may long for Orphek Atiantiks..
Point was there are cheap entry points regardless of tech...By implying LED bb's are crap compared to MH isn't fair.. or frankly nice even if true
on a certain level..
