Anyone ever use these lights?

I’m looking to setup a light dep greenhouse. Would these be a better option that the flat grid led lights ?

Nope.
The bulb in your link is 175w and would struggle in a small tent.
Look at Hortibloom Flux and Solux models. These style of light would work better in a greenhouse situation. The regular bar style led growlights (gavita, lumatek style) and even hlg style boards are more designed for multi-tier, vertical growing. Having multiole racks stacked on top of each other. Small plants, high plant count. They have coverage but not penetration. 2-3ft deep canopy, so not really suited to greenhouse application. You're more in need of penetraation rather than coverage, as coverage can be solved with simply either more units or light movers.

(I just realised, I answered your question assuming you had a large/commercial greenhouse, which maybe you dont). But even for a smalll garden greenhouse I think that bulb would do little to nothing. Maybe it'd be ok for a veg/clone light in a small space/tent).

Flat grid LED's like you call them send all their light in one general direction to maximize plant growth.

The bulb you show would waste some of it's light rays away from the plants.

If you want something that doesn't take solar footprint and can be kept further away than grid type panels maybe look into the mars hydro sp3000. I actually think they made for this use. They only take 12 x 105 cm of your footprint, just a bit more than a greenhouse steel beam in width.

Well it does look a bit like light deprivation. It doesn't take a lot to keep a pot plant awake though. They are one of the more light sensitive plants.


Light deprivation, is pulling over a blackout sheet to deprive them of light. It's a technique to get them to flower outdoors, when the sun is up too long. Generally people will sheet them over before sunset, and take the sheet off again at some point after sunset, being mindful of any damp issues. Some people just have a poly tunnel frame for this, but no poly. Thus sheeting can be an extra mold issue.

Is this thread about night break lighting? Where a lamp is used for a while, to break up the 12 hour dark period and this stop flowering. A technique used to veg plants nice and big within the tropics. Where 12/12 can be the norm all year.

Thats a great point well made. I just assumed the OP meant supplemental greenhouse lighting. But you're right, he stated light deps, and you wouldnt need a bulb for that you'd need blackout material.
You probably wouldnt need supplemental lighting if you're depping, as you'd aim to use the strongest sun to flower (summer) and just cut down the hours.
You'd only need supplemental lighting if you planned to go on growing into the darker months and by then you wouldnt need to dep.

No, that light wouldn't be strong enough to help you in a greenhouse. I use a 400-watt HPS to regulate the photoperiod and it works very well. Plus it's a great heater too. .

There was one old timer on here who said he used a single 100 watt bulb for one hour in the middle of his lights out to stave off flowering. His schedule was 12/12 to save on hydro. I can see that working, but you'd take a huge DLI hit which is probably the most important for plant growth. The only time I'd do that is if I lived closer to the equator.

A couple people on here are from Ecuador. They can tell you, at 6am someone flips a switch and the lights come on, and at 6pm someone flips the light switch again and it's lights out. Seriously, I'm on the ocean and the sun moves below the horizon faster than you can grab your camera. It's so fast, it's comical.

I think these leds can be useful, if you want to keep your plants in veg mode in early spring. Also look at cfl lamps, i would use 4000K or higher K for this purpose.

Cheers

I'm totally off topic here, but once scouting gorilla plots by a major road, we were pinned in when plane loads of parachute jumpers started falling out the sky. Hid in a ditch, with no break in traffic that coincided with a break in jumpers, we watched the sun go down for about 2 hours, thinking it was going to take 20 minutes lol




Extending the day with electric lighting is nice, if you have the power and a location that's not like 'saving grace'

 

[exploziv]

You don't need much power to keep them not flowering, tho!

 

[Daves_not_here]

Yes I was asking about these lights to keep the plants from flowering in the winter months when the days were short

Shape and light profile is similar to an old fashioned vertical 1000 watt Metal Halide.

With a good reflector, e.g. the Cone shaped reflector, would work just fine.
