Hey I'm currently eyeing LED's but would like to know if there's one geared specifically for bloom? I like the description of the TS-3000 but how is it compared to HPS?
LED for Bloom?

A lot of them being sold have switches for veg/bloom. Generally they are geared more for bloom than veg but not so much to require more than one light source. https://www.alibaba.com/premium/led_grow_light/3.html

I have a TSW-2000 and it roughly compares in spectrum to an HPS. My flowers are still mostly flower with a low leaf ratio like HPS. Penetration depth is lower and to be expected.
The FCE-3000 I have is a better quality/spectrum and a light bar style.

I have a TS 3000, I use it in a 4x4 tent and with good results, I have some pics on the mars thread.
Hey Douglas.. are yours in a tent and if so what size? I was thinking a 4x4 with a tsw-2000 and 220 watts of supplemental uvb t5’sI have a TSW-2000 and it roughly compares in spectrum to an HPS.

T5's are a lot of heat. Not very efficient either, since 220w of LED does much better.
TSW-2000 is nice in a 3x3, a TSW-3000 is better in a 4x4.

So you think LED’s provide enough UVB for tropical lines? The t5 bulbs I use are 75% UVBT5's are a lot of heat.

I’ve always gotten better results from CMH indoors over HPS alone and believe that is because of the additional UVB provided. When I used HPS with the mega ray zoo lamps added the results were better as well over HPS alone. UVB is only turned on in spurts of 15 minutes

Nice pics sativafiend. Do you have any experience with CMH indoors as well?

no CMH, just HPS and LEDs, I am just trying to give you an idea on what a TS 3000, the fce's look nice and I would have grabbed one but the price for the TS was not to pass up

CMH and HPS does not produce any UVB because of the outer glass bulb absorbing it. They do produce UVA.
- Ultra-Violet (UV) light: High intensity discharge lamps generate substantial UV internally, often the particularly nasty UV-B variety. Unless designed to generate UV (for medicinal purposes, photoengraving, or whatever), the short wave radiation will be blocked by the outer glass envelope and/or phosphor coating. However, should the outer envelope break or be removed, the lamp will still operate (at least for a while - some have a means of disabling themselves after a few hours or less of exposure to air). DO NOT operate such a lamp preferably at all but if you do, at least take appropriate precautions to avoid any exposure to the UV radiation.
The CMH emits small amounts of UVB. Just place a UV light meter under the light and you’ll see

315 W Ceramic Metal Halide (CMH) lamp is specified as producing 3.45 mW/cm2 of UVA, 0.01 mW/cm2 of UVB, and 0.03 mW/cm2 of UVC. You are right it does but it's almost all UVA
If the budget allows, pls have a look at our FCE-4800, which is bar-style design. Higher light efficiency and more uniform Par distribution than TS3000.

Thank you for the input. Do you have any comment on the output of UVB light from your LED's?If the budget allows, pls have a look at our FCE-4800, which is bar-style design. Higher light efficiency and more uniform Par distribution than TS3000.
