Lmao I'm not saying anything about the lights I agree they need more light. I was just pointing out. The bulb is not 19.5 w like was stated . It uses 19 to give u the equivalent of 250 .
My girls are dieing..

Righto now I am confused u say 19 is actually 250 but u say u know u need more light? I’m sure if 19.5 was really 250 that would be plenty of light ahwell good luck anyway

It's like me saying the ts1000 is only 150 or 350w because that's the power it draws

Yea it's quite confusing but whatever the power draws from the wall that is the power of the light, so the ts1000 is not 1000watts neither are your 19.5w lights 250w. Sorry my dude

If I could just take one more stab at explaining why I think the way I do. I mean no disrespect in the end please do you, if you prove me wrong.... great.
The Spider ts1000 doesn't say anywhere that its a 1000w HPS replacement. In fact spider is one of the only ones that don't say this because the comparison to watts is a marketing scheme. They know you are going to zero in on that number when in reality that number means nothing and just a rough estimate at best (it used to mean something before LEDs came on the scene, as you knew exactly what you were getting with a HPS light). What I been looking at is the umol to compare. A 1000w HPS generates 1850 umols and even the spider farmer doesn't generate as much, even though people enjoy the spider over HPS and apparently their plants do too. This is why we don't look at the '250w' on the box for your bulb. In fact we don't even look at the 19.5w on the box either. It means nothing to us and the numbers that do mean something isn't there when we look it up. You would be better to look into what umols or lumens mean and then buy a light accordingly.
The reason I don't think it's the nutes is because the light dictates how much nutrients the plant is going to absorb and use. If the light is low the plant wont absorb as much and will even show deficiencies.
Please don't think I am trying to be a bitch. My only intention is to help you.

Have you tried taking the covers off the bulbs ? I know some people do that if all they have are household led.

What Is The LED Watts Equivalent?
August 5, 2020
As technology improves, our language around it evolves as well. What we once used to measure quantities may no longer apply as more and more strict standards are devised with time.
Measures and units like horsepower and candlepower have an apparent history of how the measurement must have come around. And they are still used, but they don’t necessarily mean the same thing anymore.
Similarly, the wattage of a bulb has been conventionally associated with how bright the bulb will be. In contrast, watts have little to do with brightness, and everything to do with power consumption.
With the everyday use of LEDs nowadays, using wattage to predict brightness does not make sense any longer. The new measure is lumens or watts equivalent to help with the transition.
LED watts equivalent of an LED bulb is the wattage needed for an LED bulb to tally to the conventional bulb’s wattage and the associated lumen rating, in order to get that same brightness in the LED bulb.
What Is The Bulb’s Wattage?
Let’s take a quick trip down memory lane to science class in high school.
Watts, or wattage, is the measurement of electrical power, where 1 watt is equal to 1 joule being transferred per second. But in the setting of electrical circuits and application, watts easily translates to current into voltage.
For example, a 40-watt bulb would convert 40 joules of energy into light output and heat output per second.
How much of this output is heat, and how much is light, is the big energy-saving difference between LEDs and incandescents.
Merely stating, watts only measure energy consumption. It does not now, or has ever before, measured brightness, color temperature, or any other specifications that factor into a purchase of a light bulb.
Brightness was associated with the wattage due to an acquired experience of judging the brightness of a 60 Watt incandescent versus a 120 Watt one.
But now, if you go out and buy a 60 Watt LED bulb, you will most likely end up lighting up your whole street! It is just too bright for the same watts.
Now, brightness is best and most accurately measured by lumens, and color temperature is measured in Kelvin degrees.
LED Wattage Equivalent Explained
Now let’s suppose you have always known a 60-watt incandescent bulb to be a certain brightness in your experience. You associate 60-watt with that brightness level.
That level is, in fact, 800 lumens approximately speaking.
So an incandescent that outputs 800 lumens uses 60-Watts to power itself.
Now comes the beauty of LEDs. An LED bulb will use around 1/10th the wattage (6 Watts) of an incandescent bulb to give you the same, or equivalent, 800 lumens bright light.
An LED will have a wattage between 7 to 10 watts only, and that is the watt equivalent you need to look for if you are in the market for a ‘conventional 60 Watt light output’.
The LED uses 1/10th the wattage, which directly translates to 1/10th the bills you will be paying and the savings you will enjoy due to the energy-saving technology of LEDs.
Why Is Wattage Not An Important Measure Anymore?
Going by wattage to predict or determine brightness is not the standard anymore. The wattage of a bulb is simply a measure of how much power is being consumed by your bulb.
With lesser watts, an LED can give you the same brightness as an incandescent bulb of higher wattage.
This is because the wattage to light and heat output conversion is highly inefficient in incandescent bulbs.
Specifically, around 90% of wattage, power, or energy conversion is LOST as heat. Only 10% makes it to your room as light if you are using an incandescent bulb.
This is why a 90% lower watt LED bulb will shine as bright as a high wattage incandescent. Almost all of the lower watts in an LED are converted into light output.
Basically, wattage does not reflect the truth anymore, purely because LEDs are so efficient that 60W LEDs will be massively bright, compared to the 60W incandescent bulb.
Since incandescents are being slowly phased out, and the newer generations are shifting onto LEDs and other energy-efficient bulbs, the conventional measure of wattage will eventually die out.
LED vs Incandescent vs CFL Wattage Conversion
Take a look at the table below and keep it handy when you make your next purchasing decision about replacing your old inefficient bulbs to energy-saving LED bulbs.
If you are used to an incandescent bulb of 100 Watts in your living room, the LED wattage equivalent will be an LED bulb between 15 to 20 Watts. This will give you a brightness of 1100 lumens that you were used to.
Usually, since you will end up using lesser wattage, you don’t need to worry about exceeding a fixture’s requirement of a certain maximum wattage.
However, it is possible you may replace one incandescent with multiple LEDs. Therefore, it is always important to double-check that your new bulbs in total do not exceed the maximum wattage of the luminaire.
Final Words
LED watts equivalent readings are not hard to grasp once you realize that it is in fact lumens you need to be worried about, and not wattage.
Use the table to find out the equivalent, and you will end up with the correct brightness for your space.

It is only 100 watts. I use one.
The name or the "equivalent" doesn't mean anything.
They put tons of little diodes in LED lights. Then claim each one can push 5 watts. There for it must be 1000 right? No it is not 1000. None of those light receive 5 watts. Its 100 watts distributed through the tons of diodes.
But again still only 100 watts.
You also have issues with spectrum with those bulbs. Might be fine for veg tbh. But once you go to flower you will keep getting crap results.

As frustrating as this thread was in the beginning it ended up helping me a ton. I am stuck with a decision: buy a second 1000w HPS or buy the equiv and run it along the existing HPS, and eventually replace to be all LED. In your humble opinion Wiz, what would you do in your household? I will appreciate your answer. Oh for a 4x6 F/D hydro setup btw.

I haven't grown with HPS. My friend does. He just grew one of the stardusters under his HPS and it came out marvelous. Im running the starduster now under the Spiderfarmer TS1000. So I dont have an answer for you as I have yet to see the final products from both. Sorry just honestly here bud.
.
But the general rule of thumb is more watts more buds.
From what I've seen its roughly a gram a watt with HPS.
1.25-1.5 for LED. You would need a strong LED to match 1000watts.

Thanks! I been stuck on this dilemma for a while. All I know is HPS so I been trying to research like crazy on those LED lights. I end up getting really confused. As you see in a earlier reply I been measuring umols but I see you and others talking a lot about Lumens or lux. Maybe my measurement of photons doesn't mean much. I believe the spider TS-4000 is the closest thing to a 1000w. Sorry rambling. Thanks for being honest
