Well hello there 
www.ledtonic.com
We made a bulb panel type grow light called the Q2. It's fitted with 96 Samsung LM561C diodes and runs at 36W. We have 1-packs ($55) in three different CCTs, 3000K, 3500K, and 4000K and 2-pack ($99) with 3500K.
Would be happy to provide more info if you could explain how your grow setup/area looks like. Are you looking to grow clones, seedlings, veg, or full cycle? How large area are you looking to cover?

Yes, its an easy option.
But i meant reall standart led bulbs around 10watt.
Founds some cheep ones for 70cents each 10w bulb. I think they say 90lm/w in data sheet.
But i think its more. And i cut of the white Plastik bulb.
Testet 1 bulb with luxmeter 10inc distance Resultat was +-20.000lux
I didnt found any led bulbs with a samung diods (lm561 or lm301)
But i would be happy with any Infos about bulbs that have min 160 lm/w

I wouldn't use a 70 cent led bulb in my lamp let alone a grow. There are a million better options to save money. You'd probably be better off with a small t5 than 20 of those cheap leds. Hell, you'd probably be better off with 2 normal price walmart leds than 5 of those.
Not all diodes are created equal.

The pakage says around 1050lm each bulb.
Same as phillips bulbs for +4€
And when i meassure my t5 i get 10.000lumen but direct under it (1inc) .witj one of these bulbs 20.000lumen at 8-10inc Distanz
But i total understand what you say.
That is just a test for me .
I want to know what thes things can do. 100w=7€ no balst needet !
i dont even juse lampholders just wire ,white wood board and some hotglue hardcore diy
And i will test the Lumen, if i dont like what i see i will be a vegetativ light

Lumens are for humans
I don't know of any of LED bulbs that are as efficient as the top LED, but they sure are cheap. Some info on lumen increase from removing the domes.

Many cheap LED bulbs have absolutely terrible power factors. A bad 14w LED bulb I have actually draws .19 amps @120v VA=24, watts=14.3
Power factor = 14.3/24, approx 59%. A good quality bulb will have a power factor of 95%. You have to look at the printing on the bulb to see
mA number and do some rough arithmetic.

You nailed it on cheap electrical components / horrible driver design.
I keep wondering the same thing on why home center led bulbs seem to be stuck at the same lm/w efficiency as compact fluorescent's.
The one exception I have found is T8 and T5 LED replacement tubes which can be readily found at efficiencies up to 140 lm/w even with the frosted diffuser in place (which I am a major fan of leaving in place)
