LED Filament Bulbs - Where is the Tech Going?

As the title suggests, anyone have any insight on the filament style led bulbs hitting the market hard?
Will we see 500W light sabers at some point?
These are hitting in the 100lm/w (I know wrong measure) range.
Maybe good side or intracanopy lighting?

::makes scrog net out of LED filaments::

I'm pretty interested to see if this has potential, but my guess is that it's probably less efficient

I've looked into them. Very inefficient.

They are made to look good not for an efficient light source.

The filaments are connected in series and there are about 25 LEDs in each filament.

Most these "60W eqv" filament LED bulbs are in the same class of 7-10 Watts.
Typically 75 lm/W

For example:

5 Watt, 375 Lumens, Filament LED Bulb

FROM THE US PATENT OFFICE




The LED light bulb includes, in its base
#10 hermetically sealing the opening of a glass cover
#12, a control board (not shown) that converts commercial electric power into electric power for driving the LEDs.

_________________________________________________________________________________________________




The bulb base 10 is e.g. but not limited to an E26/E27/B22 connector. If being applied in a small LED light bulb, an E12 connector used in a small nightlight can be adopted. If being applied in a large illumination lamp, an E40 connector can be adopted. According to one embodiment of the present invention, an E27 connector is adopted for illustration and shall not be a limitation to the scope of the present invention.

The insulation part 20 is disposed on the bulb base 10, formed as e.g. but not limit to a hollow barrel-shaped structure, and formed with an accommodation space 21, the bottom thereof is formed with a thread 22 for being screw-fitted in the bulb base 10, two sides thereof are respectively formed with a fasten post 23, the top end of the fasten post 23 is formed with a fasten hole 24. Wherein, the insulation part 20 is made of a plastic material. In addition, a slide groove 25 is respectively formed between the two fasten posts 23 of the insulation part 20. Moreover, the insulation part 20 can be served to insulate the power module 30 thereby complying with relevant safety regulations.

I can't see any benefit in using these over regular led bulbs, at least those have chips directing the light downwards whereas these will be throwing light everywhere like CFLs.

Good for that retro look in the house while conserving energy and less bulb changes from traditional counterparts , nothing more == doing exactly what they are designed for. Omnidirectional light output makes them inferior to most other led alternatives for growing imo.

Have a couple (lightsciencegroup, ecosmart brand HD)that replaced my ugly Cree bulbs in open fixtures..... love them...... so far: )

Or when that 500W Light Saber comes out the Vert growers will go crazy, right @ttystikk ?

I'm not aware of this light. Got a link or pics?

500w version is never gonna happen due to electrical design constraints.....internal driver, thermal management, etc

It was just a hypothetical lol
Never know, next week there could be a new advancement

More fixtures with manageable output is far superior anyway. I'm all done with big single light sources, I was never happy with the light distribution from 1000W HID.

#12 consist of the same a BP5132H linear drive IC I'm working with. They have the ability to limit current when temperatures increase... and they only can dissipate 1W max of heat
