Looks like you can get the Greentek you linked to for $30 ea. (unknown shipping)
through their website. Both Hyperikon and Greentek claim 180º apertures on their respective websites and have active UL files.
Thanks for finding their shopping site. I never saw a "buy here" link on their main site.
I put 4 in a cart and shipping to AR is $16.38, making the bulbs 34.09 each, $5.61 savings over the Hyperikons. I had noticed that several reviewers complained about the Hyperikons sagging in the middle. Which they acknowledge by offering free support clips, but only if you call and request them. I chatted with someone from GreenTek and they said their bulb has an aluminum housing and "is designed not to sag". So now I am leaning toward the GreenTeks.
Trying not to muddy the water with too many choices, but I have to ask: What are your thoughts on
this bulb? It is more money,(also available through
Amazon for a little less) 4 more watts, but they claim a 240 degree beam spread and 4400 lumens. I notice some reviewers are replacing two florescent tubes with one LED. I am using Phillips F96T12/CW/EW, 60W Alto tubes (339945 product # on the case). I can't find any info on that tube from Phillips,
this is the closest data sheet I could find. It shows 4200 lumens. I realize you can't make a direct comparison in lumens because of the different light patterns. Also, that bulb is only available in clear, but my fixtures are at 12', not sure how that would work. For the other LEDs we have discussed I was going with frosted, per your recommendation.
The two rows of LEDs in that bulb, angled to each side should accomplish what I was thinking of doing with two bulbs aimed to each side of the fixture. I am probably over thinking all of this, set me straight.
Thanks, jp
