What is the light output (300 watt unit) &amp; coverage compared to a T5 Grow Light (2ft 4Lamps) DL824 Fluorescent HO fixture sold here on amazon?

I got 2 of the 600 watt leds so I'm not sure about the 300 watts but the two 600's pull around 400 actual watts together and run on less amps then the one 600 watt hps light they replaced and run a way cooler... The 600 watt leds say they cover a 6-7 foot flowering I would say it's more like a 4x4 area but that is still better then u will get with any 2ft 4lamp also remember that with most t5 lights u must buy the veg and bloom bulbs separate and the leds can be used for veg and flower

I ended up returning this fixture because it was a little bigger and bulkier than what I wanted. Check out lumens.com. They have tons of selections and their customer support is probably the nicest and most helpful of any website I have ever dealt with.

I am pretty sure it is very low, led's don't put out many lumens. Lumens is a measure of light humans see. Par is what plants see. I found a watt to lumen calculator online. Seems to be about 18,000 lumens, From what it says a 300 watt led puts out.

It's 30 watts. Watts is not a measure of light output but a measure of electrical consumption. LEDs are far more efficient vs incandescent. This LED light should work quite well for you as well as using 470 watts watts of electricity!

Save your money and buy lumatek. Apollo is junk. On average, you will need 50 watts of light for every square foot of floor space that you want to grow on. If your space is 10 x 7 (70 square feet) you will need 3,500 watts. If your floor space is 10 by five you will need 2500 watts. Spend some money on ventilation as those lights get very hot and will fry your plants. Lumatec has a ballast that will fire 400, 600, and 1000 watt lights which allows you the flexibility of changing your garden according to different lighting requirements.

I don't know what the exact lumen output is, but our basil plant did really well under its light at about 6 to 8 inches away while the glow panel was new. Unfortunately, the life time of this device is not good. The LEDs, especially the blue ones go dim or die outright in less than a year at a usage of about 10 hours a day. After enough LEDs fail, the whole rest of the array no longer lights up at all. I would rate this grow lamp much higher, if the LEDs were individually user replaceable and purchasable at a reasonable price each.

Hydroponics stores, nurseries, and places like home depot, do it center, etc....make sure you get the RIGHT ONES.....the T5 HIGH OUTPUT because they make weaker bulbs that will fit it....and make sure it's in the same "K" bandwidth as your old bulbs.

This light will draw about 400 watts. Your 250 watt mh will cost less to operate because it draws less power. Which offers better light? As someone who has used both,I prefer the t5,which can be very close to the plants, over the mh which cannot be placed close to plants.

I cannot give you an answer. Going to the "contact us" on the manufacture's website is your best option.www.dlightdesigns.com I have seen the unit at the high setting. It appears to be equivalent to 50 watt or higher bulb. Hope this helps.

40,000 lumens.. each 53 watt tube puts out 5000 X8 = 40,000. I have several of these fixtures for several years and and grow and bloom very light demanding Cattleya orchids under them. This is a beautiful, highly efficient unit. You can grow orange trees under it. It does not radiate a great deal of heat, but the light can make a New Englander think he is in Florida in the dead of winter.

It's a little over 100 lumens. Those who wrote 200 and 300, are only comparing output to generic lights that are fraudulently rated higher than their actual output.

For a 400 Watt HID light source and assuming you're growing plants that require high levels of light a 4X4 foot area is suggested by experts. Given that the reflector you are considering is somewhat adjustable, I would suggest that you can expand the effective lamp coverage in square feet by putting plants that require less light on the outside fringes of the 4X4 foot area and if needed tweak the reflector (spread the gull wings a little) to broaden the light spread. Don't be afraid to experiment. Plants are forgiving,just go slow. Height above plant canopy for a 400W HID: 12 to 14 inches. If plants show signs of heat stress (burnt leaves an obvious blunder) increase distance. Seedlings and clones require less light so turn the ballast to a lower intensity and increase incrementally as the plants gain strength.

Short answer much as a 400 watt ballastThere are also different bulbs for different applications all with different spectrums/lumen outputs it keeps nodes shorter (doesn't reach from heat stress) bulbs average 1600 lumens per

I am assuming you are asking about 4ft fluorescent vs our LEDs. The 4 ft Fluorescent T12 tubes use 40 Watts per tube. T8 lamps use 32 Watts per tube. Our 4 ft shop lights has two strips of LEDs, each 12W. Our total 24Watt LED shop light puts out light equivalent to 80 Watts of T12 ( 2 tubes x 40 Watts per tube) or 64 Watts of T8 (32W x 2 lamps). An incandescent bulb (100W) puts out about 1100 lumens, so our fixture puts out about as much light as 2 100 Watt incandescent bulbs.

According to the "National Lighting Product Information Project," 24w on this size bulb is High Output (T5 HO). A Standard T5 lamp of this length is 14w. Google: NLPIP What T5 lamps are available?

I do not know the exact lumen output.... But I would guess it to be around the 1800-2500 range. I basing that on how it compares to other LED lights I own with stated lumen ratings. I do not know The warranty length either, but LEDs in general are known for their long life, and I can say that the housing on these particular lights are very durable... The two units I purchased have endured constant salt water sprays, occasional contact with petroleum based liquids and frequent cleanings with a 4000 psi pressure washer. They have been left on continuously for several months without over heating. Highly recommended. P.s. These are installed on an oil rig in north Dakota.

Alot depends on the size of the existing lamps (PAR38 100w?) and the height at which the fixture will be placed. Since it sounds as though this is for the function of the deck Vs just security I would go with a higher output. Haveing said that I would definetly reccommend LED for energy conservation and they attract "less" bugs. Good Luck
