LED Light Stringer?

I was at Costco the other day and they have outdoor light strings that take A19(I think) comes with standard 11 watt bulbs, and has 25 spots for bulbs, cost $50. With the standard bulbs the stringer would suck for growing. But what about replacing them with 8.5 watt 60 watt equivalent 800lm, bulbs from homedepot. I know people were testing this type of concept out about a year ago. But the prices have dropped a good bit sense then and I have not seen any recent threads about this.

The biggest issue I am having is that I cant find anything beyond just the Kelvin temp for lights, I can't find spectral graphs to determine with bulbs would work best. Does anyone have the spectral graphs for the Philips or any other Home Depot LED Bulbs?

In theory:
$4-8 per bulb, 25 bulbs, $100-200
Stringer for bulbs, $50

$150-250 per string
25 blubs X 800lm= 20,000lm
8.5 watts per bulb X 25 bulbs = 212.5 watts total

Given these numbers are as good as you can hit with some off the Vero and Cree COBs, but there is essentially no building required. With 25 light sources there would be super great distribution of light over hte canopy of a great string for supplemental lighting. Runs out of a standard wall outlet.

but 8.5w for 800Lm= 94 lm per W

so why not just use HPS its more efficient and costs less?

Heat, spectrum, light distribution, supplemental lighting. I have a friend, who has a room with a low ceiling, that already has HPS lights in it and he wants to supplement them with LEDs. My company already designed and built a 330 watt, 3 Vero 29, in a 2" wide, 16" Long, 8" tall housing, which works great, but not for this application. The Lighter LED 300W series output a lot more light, but the light is all concentrated and wont work for this application.

then T5 its cheaper and the same efficency


sorry I see u are set on this and just wanna know the Spectrum

goodluck

Not set on anything, just doing some research and getting opinions.

You can not simple make an apple to apples comparison in regards to efficiency, you would have to consider the relative PAR function of each light source. This is not to say you are wrong, just to say you can not make such simple comparisons. You also need to consider light distribution and relative intensity at the location that you actually want a light. I would be able to cover 2x the space with a string like this when compared to a T5, also more control of the lights being where you want them.
