"Anyway, the guy that he knows did the mathmatical
conversion and concluded the lights were using 130watts."

I would like to have him show me that trick, as you can't. A bulb could be

6,000 lumens
and be 100 watts or 6,000 lumens and 200 Watts. I think you misunderstood

what he was
saying. 1 watt at 555 nm = 683 lumens and different nm will give a

different lumen. But
then again if he was using a radiometric spectrophometer he could measure

the output of
different nm ranges and convert to lumens, as each nm value would have a

different peak
wattage and adding them up would tell you how many watts of light are

being produced or
delivered from the but not what the lights were using. It takes wattage to

just get the
bulb going before there is any light produced.

Well, this is way over my head. I'm gonna keep my mouth shut until he shows
up. Then you can bite HIS head off! =)

That would depend on allot of things, e.g. ballast, what " soft silver metals"are being,
ratios of those, metals, bulb type and size of lamp(wattage),etc. and do we only include
visible light.

In short here is an example of a common MH lamp

..........hmmmmm can't find my MH one Psz, so a 2 lamp one will have to suffice and it is
scary. Lets say I under estimated it :-) A MH would be close.

Energy Emission 4-foot GTE 40W T-12

UV = 0.16 W
Violet = .72 WW
Blue =1.98W
Green = 2.35W
Yellow -1.74 W
Orange = 1.69W
Red 0.18W

Total watts of light delivered = 9.45 W = 100 % or 25 % of the 40 W is for just light and
the other 75 % or 30 W is to drive it, plus it by-products. And in the other post I said
40 % for light 60 % to drive it

And to add some more from a similar lamp but divided up with more meaning

100 % = 40 W

60 % UV, 24 W, that gives 21 % light + and an additional light of 2 % from the original
input energy for a total = 23 % or 9.3W

38 % heat from the original input and 39 % heat from the UV for a total of 77 % using 30.7
W

Of that 77 % , 36 % is infrared , 14.4 W and 41 % is convection and conduction for heat at
16.3 W

So 77 % for heat and IR and 23 % actual light

16.3 + 14 .4 + 9.3 = 9.3 W of actual light

: Yes Pszemol, the actual watts of light a bulb produces is way below its
: "power consumption wattage."
: A 100 watt bulb of x type may only produce 40 watts of light
:
: So bad? Only 40%? What could be the max efficiency of MH light source?

Thanks - if you ever find similar detailed info for MH I would appreciate this.

Yes, let me know if you like them. I had no issues with them at all.

I have seen the Phillips 6500K bulbs at Home Depot here in Halifax,
Nova Scotia. I bought two the other day for $5.99! I'm going to try
them on my Icecap 660. I'll run two of the Phillips 6500K (Alto series
I think) with two URI super actinics.

I'll keep everone posted of my progress.

Mort,

VHO bulbs must be replaced every six months. So if you want to save some money
you can buy Sylvania or Philips 6500K bulbs at Home Depot or Lowes for ~$4.50
each. Great price. IceCap ballasts will overdrive them from 40w to 110w each,
but it will shorten their useable lifespan. In six months, their usefullness is
over. But that is okay!! It's time to replace them anyway.

If you don't change out your bulbs on schedule, you can end up with older bulbs
that shift in color spectrum which fuel algae outbreaks.

VHO - 6 months
MH & PC - 12 months.

Is anyone here familiar with overdriving NO fluorescent tubes?

I met a DIYer today (Marc, that's the guy I told you about with those5

stage
RO/DI units) that does this to his lamps.

Apparently you replace the balast with a higher output Electronic ballast
(About $10 from home depot) and it can double even triple the wattage of

the
bulb. It operates at a higher frequency and does not shorten the life of
the bulb much at all. He's had a setup with a twin 30w 36" fixture that
with this balast is putting out 130watts after 1 year.

Will this trickery work for marine aquaria and corals???

~Mort




For anyone who is interested, I just finished overdriving a small fixture
for a freshwater tank. The difference is amazing. However, I do not care
for the color of these cheap bulbs. Part of the problem is that they are
15" tubes so my selection is very limited at the hardware store. All I
could find out about these buls is that they are "cool white" but overdriven
in a tank they are yellow, almost green.
Anyway, I can pick up some 18,000K bulbs for $10ea or get the "aqua-glo"
again for $10/ea. I know this info really isnt that useful for reefs (my
apologies) but I figured I'd follow up for archiving purposes. HTH

Mort,
you seem to getting the same results I did some time back. If I may ask - what
sort of ballast are you using? That's kinda the difference between King Marc's
experience and mine. I used the PFO electronic while he used the Icecap I
believe.

Hi James,
I used one from the hardware store mfg by Sylvania. Again, the only
thing I know about the bulbs is that they are "cool white" I have no idea
what their actual Kelvin rating is. I found some 15" bulbs at an LFS that
are 18,000K. I think I am going to try them.

I just found it on-line. The color rating is 4200K

Mort, what type of ballast are you using to light your bulbs? That is what
James was asking, not the bulb.

Oops, sorry I did not explain it well enough.

The ballast is mfg by Sylvania. It is a 4X32 Electronic ballast (4 bulbs,
32 Watts ea). I am running 2 14 watt bulbs with it. If you guys want the
model # I can get it for you. Lemme know. =)
