^^^Agromax is htg's brand . Htg owns that name. Now the agro max led's are actually rebranded Apollo led's from cidly. They use lower quality bin led's like epistar and epiled. They max out their led's to 700mA causing them to fail early on.. My first led was an Apollo. There's a handful of china direct led companies that are no good. The only china direct company that is good imo is evergrow lighting.. They use epistar led's . But also bridgelux. They drive their led's softer at 500mA. They have better quality pcb.
aside from china direct there's 3 companies that are. Above the rest. That will out last and outperform all other companies of led and hid. They use the very best quality parts. Apache tech. Area51 , Hans.
then there is induction. Most of the companies make poor quality lights. Their ballasts continually fail. Some have poor spectrums lacking deep red and an over abundance of green. There is only one induction company among the other 50 or so companies that uses high quality parts and stands behind their 10 year warranty. That's Inda Gro
for hid the best 2 bulbs / lights are mad by Philips and are CMH. Allstart line 860w and 330w. Highest par and cri rating of any light.
there are shady hid companies that lie about their products like solis tek. Their bulbs do not put out UV and they lie about their spectral output. They obviously lie about cri too. The cri rating on the 400w and 1000w are 70 and 75 where the 600 is 65 cri. Yet they supposedly have the same spectrum. Therefore the cri rating would be the same on all bulbs.
par is photosyntheticall available radiation. Measurement of photons given off by a light source. Measured in umole/s. The sun at midday is 2000 umole/s at the surface of the ground.
cri - color rendering index. The higher the cri the more more even the spectral distribution. The more even the spectral distribution in combination with high par numbers the better the performance.
intensity is measured in lumens and has nothing to do with plant growth. Cree and Nichia led's put out more lumens per watt than any hps. Have more intensity.
the number of watts don't mean a thing. Its all a about spectral output.
Ushio , horfilux, digilux all have a cri of around 35. Allstart CMH have cri of 90-93. Cree leds cri is 80 and inda gro bulbs about 90. The par ranges are about the same fo all lights. The hps deplete more further away. Led par numbers drop off towards the outer edge of the canopy. That's why multiple smaller panels are better than one large panel.
leds are here to stay and induction too. Not just in growing. But everywhere. Cars, city scapes, buildings, offices, signs, street lights, etc.
get with it or get left behind.
hps has 5-10 years maybe left in the grow market. They are obsolete everywhere else. There is so much money backing hps companies and they own all the other companies too. Its almost political..lol. JP Morgan is of one company that owns the majority of mercury mines. Which are used for hps. They have owned them since the 1800's. Jp morgan himself funded the first design of induction in 1886. He was not So happy with the longevity. He thought he would lose money from his mines. Of those lights were released. Instead he paid to have all production florescent lighting banned from the U.S. And commisioned incandescent and hps. Then later the E.P.A banned them. hydro shop will NOT say anything bad about hps. Or their products could be pulled. The hydro shop industry can be very shady. Alot of nutrient and lighting companies have secret shopper / spies. Cana and hydrofarm is notorious for that. If anything is being bad mouthed or sold to cheap. The spies report back and products get pulled.
you can get a 1000 w and fans for $600. Then $100 every 10 months for a new bulb. Extra $85-$100 a month in electricity. And $200-$300 every few years for a new ballast. Where inda gro has a 10 year warranty and area51 has a lifetime warranty. The lights have years and years of longevity. No bulb and ballast replacement. Electrical savings. In the long run induction and led are cheaper.
